Ive recently started trying cast bullets in my 30-06. The bullet I'm using is the Lee .308 200gr gas check. With gas checks over 34 grains of reloaded 7 I'm getting a ridiculous amount of leading after only 10 shots.
My bullets are cast wheel weights and lubed with Alox.
My goal is 2200 fps for use on antelope.
Anyone out there know what I'm doing wrong?
