Can a rifle with gain twist rifling be accurate with cast boolits? I am only aware of the Carcano using this method. It would seem the rifling would be continuously distorting the boolit surface as it passed thru the barrel. I assume the Italians chose the gain twist rifling to accommodate the high sectional density bullets they went with, but other countries designs seemed to do fine with equally long bullets and conventional rifling. Anyone here successfully used cast boolits in a gain twist barreled rifle?
