Did anyone see this episode last week on History channel? Will Hayden and his gunsmiths at Red Jacket Firearms in Louisiana built a long heavy barrel, improved lock time triggered AK that they had an ex-US army sniper fire at 100- 1,000 yds. No mention at all about the ammunition used. Really? 7.62X39MM, 2,400 FPS, 123 gr. fired out to 1,000 yards. I've seen match reloads keyhole, tumbling at 600 yds, when loaded a bit too light on the powder charge, striving for better accuracy, repeatability. Can any long range shooter out there tell me how a 7.62 comblock round that I've found to be quite erratic past 300 meters, could be fired accurately on a man sized silhouette at 1,000 yards?
