Hello, I have lurked on this board awhile this is my second post.
I have been loading some low velocity 7.62 X 39 ammunition for a bullpup AK-47 that wears a suppressor from John’s guns. I do not have a lot of experience with the way brass is treated by the AK-47 action. The cases pictured were new Winchester cases loaded with 12.5 grains of IMR 4227 and the 175 grain Sierra JHPBT bullet and gave us about 1,237 fps. This load cycles the action with no modifications, the cartridges feed well and they provide acceptable accuracy at 25 and 50 yards. The intended use is to cull feral hogs and this bullet just happened to be one of the first tried for functioning.
As you can see the cases are dented up near the shoulder. Not shown in the picture is a small nick on some cases lower down the case body which raised a sharp burr and a small dent on the rim caused, I assume, by the ejector.
Steel case surplus ammunition fired in this rifle does not exhibit as “severe” damage. Steel cases do have a lesser dent on the rim. Brass military cases do have the same dent up by the shoulder but it is much smaller. Both types of surplus cases have the dent on the rim.
Has anyone experienced similar problems with case damage from the AK-47?
I am also loading Lee 155 grain cast bullet ahead of 5.0 grains of Alliant Bullseye for 1,100 fps. While these loads do not fully cycle the action they are both accurate and quiet. The most noise coming from the action trying to cycle and then returning to battery.
