Hi all, My build is a golf ball mortar. 1.72" x 3" deep bore, 1/2 x 1" powder chamber, 5 and 1/2" OAL x 2 and 5/8 OD, 1018 steel. My question is using 2f powder, what distance could I expect to achieve @ 45 deg? No need for ball to go where no man has ever been before, but I would like a distance of 100 to 150 yds. Anyone experienced with this size powder chamber? Thanks..... Gary
