I just got this in and cast some up. They dropped at 309 and then I shake and baked powder coated and ran them thru a .311 sizing die which barely touched them. I did this because the PC was not perfect all the way around. You just can't get them to stand up.
Shot them in a bolt gun with an 8" twist 16" barrel. 2.190 COAL with IMR 4198 11.0 gr 1130 fps, 10.0 982 fps and settled on 10.3 for 1035 fps. All shot good and 5 shot groups were 1 1/4" to 1 1/2" at 50 yards. Very pleased with this first try because I have heard so much bad about this slug. Have only tried IMR 4198 so far. Will be shooting at longer range soon.

It was my FAVORITE sub-sonic bullet for my 7.62X39 Contender.
