Brass uniformity – how much of a difference is there?

Geoff 1 Comment

Brass uniformity affects a few things – but how much of a difference can you expect from brand to brand? If you have highly consistent brass you’ll notice similar life spans across your reloads, as they stretch at the same rate. You’ll have near identical case capacities, the result of uniform wall thicknesses. There’s a whole lot more to case uniformity, but what I want to focus on is the amazing difference from brand to brand.

Here’s a quote from an article on .233 brass at 6mmBR:

From a reloading standpoint, the important thing to note is the rather substantial variance in case capacity from one brand of brass to another–as much as 2.6 grains! So, you cannot assume that a particular “pet load” will work if you change brass brands–you’ll have to do new testing.

Two-point-six grains – that may not seem like much, but for the little .223 case, it’s a fair amount. Bear in mind, the brass compared in that article is mostly higher-end stuff.

Our brass uniformity test

I’ve just started loading for 7mm-08, and as I undertook loading for an OCW test, I thought I should start with the most uniform brass possible, so that the results of various powder charges are more meaningful.

I had 5 brands of once-fired brass, that I’d put through my Mossberg 100 ATR. I didn’t have a huge quantity of each, so I just took a random sample of 10 of each. The brands ranged from budget to middle of the road. We looked at Prvi Partizan (PPU), Highland, Remington, Winchester and Hornady.

Unlike the .223 test at 6mmBR, I noticed 17.44 gr difference in average weight from the highest to the lowest. This is probably a result of both looking at a larger case and also looking at wider variety of brass quality.

Results:

The heaviest brass was PPU, coming in at 181.79 gr on average. Highland (produced by PPU) interestingly came in quite different on average at 171.67 gr. The more middle-end manufacturers (we weren’t looking at the likes of Norma or Lapua here), came in more similar: Remington at 168.07 gr, Winchester at 164.35 gr, and; Hornady at 165.69 gr.

Winchester and then Hornady came in the lightest, which would hint at more internal case capacity, but you couldn’t say that for sure without testing H2O capacity, which I didn’t get into. I did the entire test using a digital scale and digital calipers, to identify overall uniformity.

Weight:

Winchester had the lowest standard deviation in weight (0.48 gr), and the least difference between highest and lowest (1.60 gr). The highest was surprisingly Hornady at 1.33 gr standard deviation and a difference of 4.90 gr between highest and lowest. The S.D. for Remington, PPU and Highland were as follows; 0.74 gr, and 1.07 gr and, 1.05 gr. Respectively, the differences between highest and lowest were; 2.40 gr, 3.40 gr and 3.30 gr.

Length:

After one firing, most brands didn’t have much of an increase in overall length. All eamsurements below in millimetres.

Brand  Standard Deviation Difference High-to-low
Remington 0.02 0.07
Highland 0.03 0.08
Winchester 0.03 0.12
Hornady 0.03 0.10
PPU 0.05 0.16

Neck diameters and wall thickness:

All brands except Hornady and PPU had extremely uniform outside diameters for their necks (0.00 mm S.D. and high-to-low differences of 0.01 and 0.02 mm). Hornady and PPU both had 0.01 mm S.D.s and high-to-low differences of 0.02 mm.

The inside diameter showed a bit more variation, as a product of both brass thickness and softness.

Brand  Standard Deviation Difference High-to-low
Winchester 0.01 0.02
Hornady 0.01 0.02
PPU 0.01 0.05
Remington 0.02 0.06
Highland 0.03 0.08

Which brass did I choose?

All of these brands had similar factory loads, with 139 gr or 140 gr projectiles. The differences in the once-fired brass was quite illuminating. Also interesting, but not deal breaking, was that Remington and Winchester both had a single silver primer out of a box of 20 cartridges, when the other 19 were brass-coloured. After this series of tests I decided to stick with Winchester brass for my 7mm-08, as it was the most uniform in every category except length, where it came middle of the pack.

It’s important to note that these were small samples, and that brass in other calibres may vary quite differently from what we saw with the 7mm-08. There are also a whole bunch of brands we didn’t consider.

However, if you’re looking at lower priced ammo to generate good quality brass for reloading in 7mm-08, my money would be on Winchester – I even bought another pack of Super X today.

 

If I had a range like this in my back yard, I may divide my time slightly differently.

Swiss 300 metre shoot – Any Sights Any Rifle

Geoff 2 Comments

There are a few centrefire rifle events every year that are just thoroughly enjoyable and worth attending. The Auckland NZDA Prize Shoot is one, as is the Thames NZDA shoot. The Hangiwera Station Sniper Shoot is definitely up there, and so is the Swiss Club’s Any Sights Any Rifle 300 metre shoot.

This year was my first shoot at the Swiss Club, although some of my shooting buddies have been going for years, and I attended on their recommendation.

An enjoyable shoot

The shoot is well organised, and is accommodating for younger or inexperienced shooters. There are club rifles available and the RO is very helpful with sighting in. The club rifles are either straight-pull Karabiners (K31s), chambered in the venerable 7.5×55, or modern semi-autos in 5.56 NATO/.223 Remington.

If you’re bringing your own rifle (as most do), you can use anything you like. If you’re really ambitious, you can try your open-sighted SKS and see what it will do at 300, but you’ll be going up against Bench Rest rifles that hit 10.1 more often than not. Most rifles on the day were a mix of F-Class, BR, sporting and service rifles. Because there is such a variety of shooters and equipment, it’s more likely that you will be competing amongst your group of friends than with the top of the table – unless you’re an excellent BR shooter.

The variety of rifles on the range is a joy in itself.

Although I knew there was no way I could beat the top BR shooters with my modest sporter, this did not diminish my enjoyment of the day at all. I’m pretty competitive by nature, but found myself comparing my scores to my wife’s and those of the other Howick shooters. It also meant I got to see a bunch of really cool guns that you wouldn’t usually see in one competition.

Three-hundred metres is a pretty challenging distance if you haven’t shot past a hundred before. There were even a few who had not shot at all before. However, with the help of the club’s rifle master, these young shooters were hitting paper in no time.

The cost of the shoot is not prohibitive, with a range of $20 on the day, and of the cost of 25 rounds of ammo. The Swiss Club has a really good website for the ASAR shoot, which lets you book your position on the mound ahead of time. With several details across a few days of shooting, you’ll definitely find a time to shoot, and you may even try and better your score on another day.

The format

The shoot starts with 5 individual sighters. Each shooter on the line takes a single shot from the prone position (all shooting is prone), after which the targets go down and the scorers call back the score and location of the round to the RO via radio. A notepad and pen are handy, as you try and figure out where your sighters are landing. The shots are called out like “9 at 3 o’clock” or “7 at at 1 o’clock”, with the first number being the score (1-10) and the position on the clock helping you to identify which segment of the target you are landing on.

After you’ve gone through your 5 sighters, there are 10 individual scoring shots, shot in a very similar fashion. Each shot is still called out, helping you adjust your shot placement, especially if the wind picks up downrange.

A notepad is essential to sighting in at 300 metres.

After the individual shots, you have “rapid” groups of 2, 3 and 5. I say rapid, but it’s really not. It’s simply a few shots in a row. There is no pressure to hurry up, and there are plenty of people single loading their shots.

All shots are still called out, except for the final group. This means you can adjust your shot placement right up the last minute.

How hard is it to hit the 10 ring? You’ll need to be shooting around MOA (just over) to consistently hit the 10 ring at 300 metres. If you want to notch up a bunch of 10.1’s, you’ll need to be shooting around between 0.5 and 0.66 MOA.

The experience

I thoroughly enjoyed the shoot. I went a bit early to watch some of my mates shoot, but also to familiarise myself with the format and calls. I did end up waiting around a bit, but I ended up being there for most of the day, as I had some “technical difficulties”.

After watching the 11 am detail, I hung around over lunch time before taking up my spot on the mound. I was a bit nervous as I was shooting my rifle in its complete configuration for the first time. Since the last time I had shot, I had fitted and bedded my Boyds Prairie Hunter stock, had a new bolt handle machined, and modified my magazine follower. Also unfamiliar to me was a 6-24 scope that I had been sent to review.

Unfortunately the scope did not perform and was unable to be zeroed on the day. This meant I had to wait through an entire detail, pushing out my wife’s shoot as well. However, I used this time to fit my trusty Vortex Diamondback 4-12×40 BDC, which I brought just in case. I have learnt my lesson with taking unfamiliar equipment to a shoot.

Unfortunately this meant I had to sight in from scratch, however, I was on paper on my 3rd shot, and the rest was just fine-tuning. By the end of my shoot I had it right were I wanted it, which meant my wife had the rifle ready to go for her shoot, and actually did quite well. Results can be seen here.

Overall I was very happy with the my complete sporter set up, and with some more powerful glass, I think I’d be comfortable taking this rig out onto the F-Class range.

Looking forward to some Norma brass at the end of this.

I think the load development still has some way to go, particularly as the barrel on this rifle is quite short. Not having developed a satisfactory handload, I shot this competition with factory 6.5×55 ammo. I used the Norma-Sierra 144gr HPBT, and the round seemed to perform pretty well. To be honest, I was more interested in the brass than anything else, as I think this rifle will prefer lighter projectiles, in the 130 – 140 grain range. Over the holidays I’ll be testing out the 129 gr Hornady Interlock and 140 gr A-max. I’ll be comparing this projectiles side-by-side with the 142 gr SMK and the 144 gr OEM projectile in the Norma-Sierra load.

At the end of the day, the shoot was enjoyable, and definitely an experience worth repeating. You can shoot multiple times on one day, or on multiple days across the competition. If I have the time next year, I’ll probably try shoot it on a few days. Being located only 45 mins or so north of Auckland, the range is really accessible, although it is also rarely accessible. The Swiss Club is, of course, a club for Swiss nationals, and as far as I know, this shoot is the only time of the year that the range is opened up to the general public.

If you would like to try a different range and format, and perhaps a longer distance than you usually get to, you’ll definitely enjoy the Swiss Club’s ASAR shoot.

3 gifts you can buy for a shooter or hunter

Geoff Leave a comment

It can be hard to find the perfect gift for someone. It can be harder if they’re into shooting and you’re not – harder still if you don’t have a firearms licence and can’t legally purchase the things they would like. However, there are a few go-to things you can consider, and they won’t break the bank either.

Things made out of ammo that aren’t ammo

Shooters like things that go bang. However, the next best things might be something that looks like it goes bang. However, not all mementos are created equal. Ask any golfer, and they’ll tell you every year they get terrible golf-club or golf-ball shaped items to bury in a draw somewhere. Every now and then they get something that’s actually kind of cool. It’s pretty similar for hunters.

A barbecue lighter shaped like a shotgun may not get someone’s juices flowing, but a bottle opener made out of a .50 cal. case with a 750 gr A-MAX projectile seated in it might just get the right reaction. Yeah – 750 grains – that’s four to five times the average .308 projectile weight. My wife and I got one for my father-in-law last Christmas – and I liked it so much I got myself one too. The brass is obviously softer than bottle caps and will mark after use, but hey, it looks so freakin cool. You can get them from Gunworks in Christchurch, and because it’s not live ammo it can be sent anywhere. They have other options too.

Another cool ammo-looking option can be cuff links. These can be done poorly or very well, so be selective. The imitation 12-gauge cuff links my wife got me are not only well made, but look pretty damn good too.

A magazine subscription

If you’re significant other or best friend has a hunting magazine lying around but they don’t have a subscription to it, that could be a great option. Look for the subscription page and photocopy or scan it, or find the magazine’s website. It’ll be pretty obvious if you tear out the page…

Make sure to take a picture of the product code so you can find what you need at the store.

While everything and anything can be found on the internet, gun magazines are a great way for shooters to enhance their knowledge of local shooting spots, new equipment or competition results.

Reloading supplies

Well, you can’t buy ammunition for your partner if you don’t have a licence, but if they reload, you can buy them everything they need to make their own. You’ll still need to have ID, as primers and powder are explosives.

How do you know what to get? Go over to their shooting bench and see what’s running low. Make sure to take a picture of the item or the product code to show the guys at the gun store. Also, make sure to shop around. When you’re spending near a hundred bucks on projectiles or a box of primers, looking at different websites or stores can save you around 10 per cent.

Brand new 7.62x39 PPU ammunition

Reloading for SKS or AK – is it worth it?

Geoff Leave a comment

The SKS is one of very few semi-automatic centrefire rifles that allow for cheap and cheerful shooting in New Zealand. The rifles themselves are amongst the cheapest autoloaders around and the steel-cased ammo is a bargain compared to other centrefire rounds, as detailed in a previous post on the venerable 7.62×39.

However, what about reloading for the SKS or an AK? is it worth it? Every armchair shooter in the world will want to quickly chime in on why it’s simply not worthwhile reloading ammo for these rugged rifles. Here’s my take on it.

You will lose some brass

There is no question about it. With almost any semi-auto rifle, you should be prepared to lose a few casings. Even bolt action rifles in military service rifle matches will sacrifice some brass here or there for the sake of speed. But the SKS really loves throwing brass away. The video below perfectly illustrates what I mean.

However, even with the brass being flung in every possible direction known to man, you will still get a healthy return if you have patience (and the grass isn’t too long). The majority of your shells will land between 1 and 3 O’Clock, within a few metres of your shooting position – but not all of them. On my last trip to the range I shot some brass-cased PPU with some friends, and we recovered 55 out of 60 ejected cases. That’s over 90 per cent of your brass coming back to you – not bad.

The other option is to have a brass deflector or catcher attached, but these render your rear sights useless. Therefore, this only really becomes possible with a scoped SKS, which, as we all know, is not the most worthwhile pursuit in the world.

You will damage some brass

Again, this is a given. Autoloaders are hard on brass and the SKS is no exception. There are extractor marks from rough ejection, and if you’re shooting over a concrete floor, under a roof or near any kind of structure, chances are your brass will hit it and could possibly get dented.

At the end of the day, a small level of attrition is to be expected – it’s the cost of doing business with the SKS or an AK.

It is not a super-accurate rifle

Look, handloading is not going to turn your 1 – 3 MOA SKS into a 1/2 MOA super rifle. It just won’t. Usually handloads can be made to be incredibly accurate, and this works because you develop ammunition that is suited to your rifle’s chamber. The SKS is an intermediate-cartridge fed battle-rifle with very loose tolerances, which aid its reliability. Remember, cheap, reliable, accurate – you only get to choose two.

If you’re reloading the 7.62×39 for a CZ bolt action or a  modern semi-auto, then you’re talking about a whole different ball game.

The economy isn’t quite there

The price of 7.62×39 ammo means it’s not really worthwhile buying brass-cased stuff, plus your other components and dies. It will end up costing about the same in the long run, and your accuracy won’t be much better.

Generally speaking you can pick up steel-cased ammo at one of the major gun stores for around $16 or $17 per 20 rounds. If you buy in bulk, you can save a lot more too. Realistically, if you’re cost conscious and like doing a lot of shooting, buying in bulk would be a better solution than reloading. Plus, who doesn’t like opening the safe and seeing a wall of ammunition?

What to feed a hungry SKS?

But I’d still do it

However, I’d still do it. And the reason is, because I enjoy shooting and I enjoy reloading. Brass cased ammo costs $8 more per packet (if you know where to shop – $15 if you don’t). When thinking about the cost of the brass, I account for the fact that I get the value of one factory pack of ammunition regardless. In other words, the brass is costing me $8 per 20, even though the pack of ammo costs $25, because I shot $17 worth of factory stuff. I say $17 worth of shooting, because that’s what a box of Tula SPs would set you back.

So, I can expect to retain about 18 cases, and I might get 5 or so reloads out of them. Throw in the cost of primers and powder (which I use for other loads anyway), and projectiles. Now, this lot I’m going to reload with Hornady’s Z-Max. In 7.62×39 the Z-Max is a SST projectile, with a different coloured tip according to Nathan Foster – whose research I would definitely rely on.

Why the Z-Max? Firstly, let’s be honest, a green-tipped bullet kind of looks cool. But also, as Nathan’s research suggests, the SST or Z-Max round is probably one of the better choices of bullet for what the SKS is designed to do – wound effectively within a limited range. I could save a few cents per round by going for a soft point projectile from another manufacturer, but I’m keen to give the Hornady bullets a whirl.

As for the cost of the dies – well, hopefully that gets absorbed over time. If not – I’ll just have to shoot some more until they’ve paid for themselves.
