Gno has it right, the sooner you remelt ALL non perfect bullets the sooner you will get consistant results. The other thing is turn the heat all the way up and use Brakeclean on your mold (make sure it is all evaporated though) before any casting. As to loading, water dropped CO (clip on) wheelweights will do 2200 fps w/a good lube, I use LBT's Blue for everything. As with anything there are a myriad of details in the casting ect. of lead bullets but the above items should get you a good start. Muddy
