AG42b ammunition question
- Thread starter rolfyrolf
- Start date
Any commercial 6.5x55, will work fine in the Agb42B.
Just keep in mind, these rifles were issued with a parts kit, including extractors, firing pins, springs and plungers.
I had a problem with the very first one I owned, that was from the first batch that came into Canada. International out of Montreal, was selling bulk cases, loaded with a very fast flake powder and wooden bullets. They included enough #44 Bofors powder (imr3031) and 140 grain pulled bullets to reload them with. Good stuff, cheap but the primers were corrosive. Not a big deal, just a pain in the butt with the Ljungman system.
Anyway, to make a long story short, I followed the loading instructions that came with the package and had a Kaboom. It blew the mag out of the rifle, along with the 8 rounds still in it down against my leg. Damn that hurt. I had a bruise that went from my hip to my knee, about 8 inches across.
The rifle was undamaged, other than a small crack infront of the mag well.
Called the people at International and they asked me to send the rifle back on their dime and by the way offered to pay for any damages to myself and if nothing was obviously wrong with the rifle, even take back the rest of the package.
After about a month, they sent me an as new rifle and explained that the first rifle had the firing pin protruding to far and as it brought the cartridge into battery, set off the primer.
This is one of the problems with the Lungman system. Other than that, they like the pressures to be around 45,000psi and hanldle it quite well.
When the Rashid and Hakim were made, utilizing the Lungman design, they included adjustable gas ports.
One thing I never did find, were any of the full Auto M42C models.
Many of the rifles that came into Canada are marked as the C model but it doesn't look like any full auto parts were ever installed.

I have load my ammo with slowburning powder imr 4350 and it still shot and functioned perfect.
Your best off hand loading for this rifle. IMR or H 4895, IMR 4064, RL 15, and Winchester 748 are good powders to use. Load 140gr bullets to 2450-2500fps and no more! These rifles were designed around a working pressure of 45000psi.
Stick to that number as best you can as too much pressure will allow the bolt carrier to slam into the take-down/Safety assembly, and too much of that, and too vigorously, will eventually break this part and the next thing in line is your face.
BTW, Winchester primers have harder (Mil spec) type cups and better resist the firing pin bounce of most semi-autos than most of the other brands.
Even with the proper loads, it will still fling cases about 15-20 ft. @ about 1:30.
If chasing cases is not your thing, then take heart, there is a solution. The screw on top of the gas block is M3x.5 which is very fine (around 50 TPI). If you can source a machine screw and nut with this thread you can easily fashion an adjustment screw for the gas system.
I will provide the link for you that explains how it was done.

Hope this helps.
