I just started shooting my newly finished Jim Chambers Virginia rifle. It is a .62 caliber. I was shooting a .600 PRB with Pillow ticking and 75 Gr. FFFG. The instructions in the kit said that not to use more powder than the caliber of the ball. Is this just a suggestion or is their limitations to the size of the charge for this type of barrel? I searched the Rice site and can't find information about it.
I am getting good groups at 60 yards but all are 3-4 inches low. I filed the front sight down more but no real difference in elevation. Can I go to a larger charge? What would be the max? Anybody else shoot this barrel?
