I thought I would cast some lead bullets for my 338 Win Mag to save some money on practice. The result was a dismal failure. I sorted out the best looking bullets from my casting efforts and sized them using gas checks. I used Red Rooster lube when I sized the bullets. The pattern, and I will not glorify it by calling it a group was all over the target at 50 yards and all over the berm at 100 yards. This is from a custom Mauser that usually shoots just over minute of angle with Speer bullets. Any suggestions for improvement would be welcome.
