Russian made ammo

[icehousebob]

We were doing some sighting in a week ago and I tried out some Russian .223 ammo. It was Brown Bear brand, with 62 grain hollow points. At 75 yards, it looked like a buckshot pattern, about 10 inch spread and about that far to the left of the point of aim. And the holes in the paper were keyholed. I switched to some Korean 55 grain ammo and then some Federal 50 grain and both shot tight groups right on center. I'm not sure if the Russian ammo is made for faster twist rifling or is just junk but its a good thing I checked it before doing any serious shooting. I gave the rest to one of my sons to try in his Mini-14. I'm not sure of the rifling twist in that one, but we'll see what happens. That ammo may be meant for M-16's and that sort of weapon. Has anyone else tried this ammo?

It is going to make a difference on what you have for rifling. If you take the M-16A1 you are only suppose to use 55 grain or less in them compaired to the more modern m-16's like the A2 and A4. They recomend the 62 grain and up. So with the higher grains it might not like them so well.

Like the above post said. Your not getting enough twist to stabilize the bullet. You probly need a rifle with a 1-8 or 1-9 twist.
