I bought a t/c mold for maxi-balls that was supposed yo a 370g but all the bullets come out 365g or less. So I took a file to the back of bullet and filed them down to 362g and the results were great. I was putting bullets through bullet holes at 50 and 100 yards. Not bad for a 1 in 28 twist that was made to shoot sabots. My load was 90g pyro premium, 362g maxi, with a button patch on the back of it with T777 primers. I shot 40 rounds on Sat. at several different targets and had bullets grouping ataround an inch all day.
