I guess I'm conflicted. I don't really care for the bright colored powder. I think a traditional lubed boolit looks right. I started casting because I needed cheap bullets to fireform 7-30 Waters. You couldn't imagine the piles of dollars I have saved.
I have mostly cast for pistols (32 S&W Long, 32 H&R, 45acp and 41mag) but have recently been playing with 30-30 and 30 carbine. I don't think I could bear seeing a neon colored boolit in a 30-30 but have decided to PC the 30 carbine to keep the gas system clean. I was playing with a copper color and eventually threw some black power in the mix and it turns out looking like dirty grease. Tolerable to my eyes.
