Gwpercle makes a very good point . As I stated above I shoot plain base bullets in my revolvers . My bullets run between 8 to 12 BHN depending on caliber & velocity . I can push them to 1300fps in magnum loads . Sized correctly & quality lube makes the difference . If one looks at Elmer Keith's cast loads he considered 8 BHN " hard cast " . Anyone who has shot his loads knows they are warm & they perform . Many are introduced to cast by buying a box & loading them up . Only to find out that they're too hard , they're undersized & lube just don't work . Spend a week scrubbing lead & then go buy plated or jacketed ever after . Cast bullets you get results equal to the effort you're willing to spend . Same old story " Garbage in Garbage out " .
