I found a CZ527 Carbine, 7.62X39, in a pawn shop about a year ago. It had a few dings and scrapes from riding in a truck rack, but the price was right, so it came home with me.
I tried it with a little bit with the Lee C312-155-2R (supposed to be "THE BOOLIT" for the Ruski Shortski) and wasn't impressed. Results did improve going from .309 to .311 then to .312, but that's all this mold will do. So it sat in the safe.
Got it out again last week and looked around to see what else I have that might fit and spied the 311407 GB mold. Had about twenty sized .313, checked and lubed with Dan's Bull Shop Speed Green.
I loaded three each with 10, 11 and 12 gr. of Alliant 2400 at 2.143 OAL to just touch the rifleing. At 50 yds. the 10 gr. load made a kinda vertical string at .527 center to center. The 12 gr. load was another vertical string at .770. I was impressed, to say the least, but what surprised me was the 11gr. load.... http://img.photobucket.com/albums/v321/KYCaster/000_0413.jpg
It's been a long time since I jerked three shots into a group like that, so I just had to try it again. Loaded up three more rounds and, dangit!, the group size almost doubled!! http://img.photobucket.com/albums/v321/KYCaster/000_0417.jpg
Don't ya hate when that happens!!!:mrgreen:
