The very FIRST barrel Bill Large made was a 1x33 octagon 58 caliber.He had no idea if it was any good and gave it to me, I made a simple half stock,silver trimmed rifle with a single set trigger,I loaned it to another shooter and he set some kind of record with it for offhand shooting at a match in Ohio.It was 8 grooves with a 1 in 44" twist and liked a .575 round ball and 65 grains of DuPont 3fg.I still have that mould.This was in 1958.
