    Left & middle were from a CMP RM1SPCLRACK with new CBI barrel while rightmost was FG with an old SA barrel (TE-2/ME-0+).

    IMR 3031 powder is quite a versatile powder!... especially with Cast Boolits.

    Thank you for sharing those pics!!! Very nice!!

    Hello Jim... I actually slugged the barrel (.30945), and checked the diameter of my cast boolits with a Mic (.313 Linotype), and believe the 311299 mold I have is a fairly good match... from my observations of load testing, and closely watching the lead fouling each time I shoot, I believe I need a little more lube, and/or more band support to ensure better alignment and rifling grip in the bore. I do know the rifling is not as deep and crisp as a newer barrel would have, but it is still there... If money were no issue, I would have that new barrel on the Garand, and have her tuned tighter than a fiddle!!! LOL!!! but it's that damned money thing....
