I just find it strange that steel cased and my handloads fired and Factory ammo failed to fire 50% of the time.
I am having a really hard time deciphering this sentence. Did you just say:
Steel cased and my hand loads fires 100% of the time.
or
Steel cased and my hand loads fires 50% of the time.
Another question for clarification: are you referring to the Remington ammo as "factory ammo?"
If you said that your steel cased/handloads fire 100% of the time, and this "so called" Remington "factory" ammo fires 50% of the time, then my advice holds true: remington sucks at everything 7.62x39.
Just because it says "remington" on the side of the box does not automatically make it correct.
I've had Federal, Winchester PMC ammo and never had a problem with them. I do have one round that didn't fire that I took apart and reassembled I pull that one and reload it with a cast bullet.
read my previous posts. Measure the remington bullet diameter. If you can't do this, and you reload ammunition, than you are doing something terribly wrong. Pull out your calipers. Pull out one of the remington cartridges. And measure the bullet on one.
You will find that my advice is correct. Just go do it and report back.
And then throw that
****ing shit in the trash (or in your case, pull the bullets and hand load your own out of that brass...)
