.308 – The Gun Rack

How to: Disassemble M305 magazine

April 10, 2016April 10, 2016 Geoff Leave a comment

The MI4 or M1A is a mainstay in most military rifle collections, alongside its predecessor the M1 Garand. The M1A even sees frequent use in Heavy Metal classes of 3 Gun competition. The Norinco M305 is a damn good copy of the Springfield M1A (and the newer ones are even better). They’re also 4 or 5 times cheaper than their American cousins.

However, Chinese guns often come dripping in cosmoline, requiring a proper birthday before heading to the range. Even parkerized magazines in sealed bags will be dipped in cosmo to keep rust at bay. If you’ve bought a rifle that’s been stored in an armory for a while, you’ll notice that cosmo and parkerized finishes interact and create a greenish-grey finish. Anyway, I digress…

If you’ve bought one of these Chinese knock-offs, chances are you’ve got a magazine or two full of cosmoline. This will mean stiff functioning and potential jams when they get dirty as well, leading to failure to feed situations. Disassembling one of these mags is easy to do, and highly recommended for cleaning purposes.

Step 1 – Remove the floor of the magazine

Unlike older magazines like the Lee Enfield’s 10-rounder, where the spring and follower come out of the top of the mag with some wiggling and creative angles, the M305 magazine has a floor plate that can be removed.

A screwdriver or something similar can be used to pry the locking tab up. Once this is over the magazine wall, you can slide the floor of the magazine forward.

Step 2 – Take it apart

Unlike rimfire magazines, there are no small springs or buttons that leap out at you when you open the magazine up. Once the bottom is removed, you’ll probably find the square spring is pressed against the tabs that were keeping the floor in place.

It’s quite easy to remove the spring by lifting a coil at a time, and then giving the follower a bit of a wiggle to get it out. Take care not to cut yourself, as these mags don’t have the best finish in the world.

The spring shouldn't jump out at you and there are no small parts to lose. — The spring shouldn’t jump out at you and there are no small parts to lose.

Step 3 – Degrease everything!

Norinco is nothing if not liberal in their application of cosmoline. The preservative gunk is everywhere. Make sure you get your cleaner/degreaser inside and outside the magazine, and over all of the parts you have removed. I personally prefer a degreaser in an aerosol can to make sure I get everywhere. Most of the time I use Wurth’s Industrial Cleaner, which is a citrus-based aerosol, and highly effective.

Give the magazine a good wipe, inside and out, with a clean rag. Again, make sure to watch out for sharp edges – maybe even debur them if necessary.

Step 4 – Oil and reassemble

A bit of lubrication of the spring/follower is not a bad idea. Not enough to get dirt and debris stuck in there, but enough to relieve some of the friction as the follower contacts the walls of the magazine.

With this particular magazine I used some aerosol Ballistol. However, a few drops of Remoil or Hoppes Lubricating Oil would do the trick too.

After you’ve applied some lubricant to the inside of the magazine and put the follower and spring back in, it’s time to close up the floor.

The curved floor metal means you'll need your screwdriver again to lift it into place. Seal the deal by tapping it closed with a rubber mallet or tap it on your bench. — The curved floor metal means you’ll need your screwdriver again to lift it into place.

Bullet selection for hunting this roar

March 20, 2016March 20, 2016 Geoff Leave a comment

For many young girls and guys around the country, this roar will be their first opportunity to hunt – or at least to hunt some of the more prized species New Zealand has to offer in their prime coats and colours. While a shooter may be proficient with their weapon of choice, this does not automatically make them a good hunter.

Aside from the bushcraft, fitness and stalking involved – not to mention antler-induced-excitement behind the trigger – a serious consideration is the choice of ammunition. Fortunately for those shooting a more common calibre, there is plenty of off-the-shelf ammo that will do the trick. If you don’t intend to shoot much aside from sighting in and hunting, then buying ammo makes much more sense than reloading.

Bullet choice in New Zealand

Some common hunting calibres in New Zealand include .308, .303, .223, 6.5×55, 7mm-08, .243, .270, .260 and .30-06. To a limited extent the old Russian military calibres see some use (7.62×39 on goats or yearlings at close range or 7.62x54R if you’re running around with a sporterised Mosin-Nagant). And .300 BLK is becoming quite popular for goat culling or in short-range (but fancy) bush guns.

If you’re buying ammo for more common calibres like .308 or 7mm-08, your store owner’s recommendation will likely be good enough. Remington Core-LOKT and Winchester Power-Point are popular choices, and Hornady Whitetail does very well in most modern bolt actions too. However, for reloaders who have been chasing accuracy, bullet choice can change the game completely.

Some of the more common 7mm-08 hunting choices.

For example, with my 6.5×55 a 142 gr SMK or 140 gr AMAX does a beautiful group at 100 yards. In fact, my new favourite is Norma-Sierra 144 gr – it’s a factory load, but I can’t seem to beat it with the projectiles I have on hand. However, all of these loads have hit-and-miss performance on game. The AMAX less so, but certainly the SMKs are not meant for hunting. They have erratic terminal performance, sometimes yawing and producing massive wounds, sometimes producing pinhole wounds that can lead to inhumane kills and extended tracking of wounded animals.

But isn’t the Sierra Match King a hollow point? Yes it is, however the HP in this projectile is not designed for expansion on game. This hollow section in the bullet is to keep weight to the rear of the bullet, stabilizing it in flight and making it a more accurate round.

The SMK looks great on paper but does not produce consistent wounds.

Factors like this need to be considered carefully, especially in calibres with higher sectional density, which can lead to deep penetration, but poor expansion if bullet choice is incorrect. This can be prominent in the 6mm and 7mm calibres.

If you’re about to start working up your hunting load for this year’s roar and do some quick sighting in, there are a few ways you can narrow down your bullet selection. You could start by checking out the forums or facebook pages and seeing what others with your rifle/calibre have been using. Or you could start by doing some research on sites like Nathan Foster’s Terminal Ballistics, or checking out the projectile manufacturer’s website. If you are the type to learn better by doing rather than reading, try a sampler pack from Gunworks to get a few different projectiles through your rifle and find its sweet spot.

3 gifts you can buy for a shooter or hunter

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.

It's hard to find a cooler bottle opener than this .50 cal case from Gunworks. — It’s hard to find a cooler bottle opener than this .50 cal case from Gunworks.

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.
