Thread: Cast bullet help

Flaring the case mouth is important with cast bullets because if you shave any lead off the bullet when seating you will quite likely get gas cutting when you fire the cartridge as there will be room for gas to blast up the side of the lead bullet which will then result in leading & accuracy will suffer.
With subsonic loads I don't use gas checks & have no problems but when I get up to 1400fps+ I have to go to checks or leading occurs but in saying that I use fairly soft metal most of the time, just straight wheel weight metal.
Cheers.
