View Full Version : Bushmaster Carbine Range Report

There was pause in today's precip so I took my year-old Bushmaster A2 AK Carbine to the range for a little functionality check with some new-to-me mags and a variety of ammo.

I had eight used USGI 20 rd mags to check for functionality, and wanted to try the following flavors of ammo:

Wolf 55 grain FMJ
Wolf 62 grain FMJ
Barnaul 62 grain HP
Silver Bear 62 grain HP
SA surplus M193 55 gr FMJ
Federal XM193 55 gr FMJ

I fired individual mags full of a given round, and went as far as to load mags with a mixture of all rounds, just to check the function.

As the weather was threatening I did not set up the trusty 20+ year old Oehler 33, and essentially fired at a large rock buried in the 200 yd berm. Again, functionality was the objective as opposed to general accuracy. At 200 yard, if the dust puffs were in the same spot, that's close enough for the A2 open sights and my 49-yr eyes.

Bottom line:

The Bushy continues to captivate me, digesting all the ammo from all mags with NO failures, even the mags containing the mixed flavors. The dust puffs were monotonously in the same spot. If they weren't dead Bad Guys, they were tightly pinned down with significant casulties, as it were.

As far as felt recoil, the Silver Bear seemed the "lightest" whereas the Federal XM193 was clearly the most stout, and threw one heck of a flame to each side of the AK brake on the Bushy. The Wolf 55 grain FMJ threw small sparks out the muzzle about every three shots or so, the only ammo to do this that I noticed.

The AK brake is effective at controlling recoil and keeping the target acquired for fast recovery and follow-up shots, although it is a bit noisy under the bench pavillion roof. No where near as loud as the mini-Y comp, though, and no backblast.

This A2 AK carbine is very nice handling, providing an excellent cheek weld with the A2 stock, and I believe that I prefer it to a collapsing style stock.

The mags worked, the ordnance was expended without incident, and I had a couple mags of Wolf 55 FMJ left to shoot when a guy pulled up with a son and daughter, who expressed interest in the carbine. I asked their father if they could fire the weapon after a brief instruction and he gave the OK. Thier father took two empty 2-liters out of the trunk and carried them downrange, while I went over the carbine with the kids. When they were ready they each fired a 20 rd mag at the bottles and chased them all round the berm, and were wearing ear-to-ear grins. So was Dad.

A good day.

That's fantastic performance from your Bushy!... and two kids who will now know the joys of the black rifle instead of seeing it as an instrument of man's doom (the way the anti's describe it).

More power to you, Noah. As I advance in years, I value being able to pass on. It pleases me to read accounts like yours. And congrats on having such a good carbine.

You guys shoot steel cased ammo in your Bushy's?

I talked to a tech at Bushmaster a couple years ago, and he said DO NOT use Wolf or other steel cased ammo in their guns. He said such ammo is extremely hard on extractors and chambers.

What do you Bushy owners think?

Yes, oustanding indeed, and :up: :up: for itroducing those young ones to the world of the " (not so)evil black rifle". I only wish I were to be so lucky as to have had the chance to shoot one at a young age.

P.S. Your giving a bad rap to the AR "jamomatics".

(The truth may be out that they do not jam every other round as thought, especially with the cheap russian ammo):D

Yes, I do, and frequently, and have been.

My preban Colt Sporter Target 20"and this Bushmaster Carbine both digest Wolf, Barnaul, and the Bear stuff without issue. Even the Wolf and Barnaul with the red bullet sealant on the necks. The only stuff that does not function is 01-headstamped Olympic, and it short-stroked

The reason for this probably lies in the fact that the both weapons are chambered for 5.56x45 as opposed to .223 Rem. The 5.56 chamber is a tad longer in the leade.

Your Bushmaster rep from two years ago is correct, they did not recommend use of steel cased ammo. IMO, not because of any hardness issue with extractors and chambers. The thin steel discs used in case manufacture must be very soft by definition in order to handle the forming and draw process without tearing or cracking as the metal tends to work harden with every step of the process. There are no doubt annealing steps after so many forming/draw steps in order to soften the steel case form so that downstream form and draw steps can be peformed. The result is the steel of those cases is a much lower hardness than the heat treated steel of the barrel/chamber, bolt, and extractor.

Think about it -- the AK was designed to handle specifically steel cased ammo, and the hardness of the case, bolt, barrel and extractor all had to be taken into account and specified in acceptable ranges on the prints. The same holds true for the AR, by design the bolt and barrel must be of an acceptable hardness because there is steel on steel every time the bolt locks and unlocks. What is so different if the case is steel -- it is still steel on steel, and the case is wickedly softer than the mating parts on the weapon.

Since two years it has been determined that the most significant culprit regarding the non-functioning of Wolf in ARs was the red bullet sealant. Current production Wolf doesn't have this sealant, and it POURS through my ARs. And the extractors are shiny, but not worn after a couple-few thousand rounds each.

Just my 2 cents.

Nice report Noah. That was my first AR, the bushy shorty ak. I really liked that muzzle brake! Not because it tamed that vicious .223 recoil, but the negligable muzzle rise. Quick follow-up shots were very accurate. And I feed my AR's wolf regularly also with no problems. Again nice report.

I just finished up a case of 500 rounds of Wolf. It was the 62 grain stuff without the red stuff. I've found out that the new production Wolf ammo is not coated with laquer. I used all 500 rounds without a problem, or hiccup. It's pretty accurate as well for cheap plinking ammo. I've had a few problems with the Winchester 55 grain stuff. I've had a few misfires with it and the accuracy sorta sucks with it. I'm pleased with the Wolf 62 grain stuff and will continue to use it.

A:eek:

Andy:

Thanks for the chime in; that's exactly what I've seen with Wolf 55 and 62, and the Barnaul Silver Bear 62, but both of my Bushmasters and the preban Colt ST have 5.56 chambers, too.
