Having a bit of trouble getting proper fill out on a 500 gr Accurate mold for my .500 Linebaugh. I know the issue is not the mold, as Accurate molds are superb. I have run it hot, and bumped tin content way up. No improvement. Bullets are shootable, but not what they should be. Lots of wrinkle around/between lube grooves. Mold way sprayed out with brake cleaner, had some wrinkles, then cooled and scrubbed with Dawn and a toothbrush. Still no change. I have never used a mold over 240 gr, so maybe I'm missing something. On another note, boy does this thing overheat fast!
