Hello!
I just tried 220 grain bullets cast from straight wheel weights in a Lyman mold, Lee Liquid Alox, with gas checks, over a minimum charge (according to the Lyman manual) of 5744. Eureka! They shot great at thirty five yards, especially as I was leaning over the pickup tool box on a windy day. Groups were an inch or less for five rounds so I'm sure they'll do much better when I can shoot off the bench. They also feed perfectly, so I'm just pleased as punch! They'll work great as the next cowboy match.
