I just use the one that came with the Rockchucker Supreme kit. It doesn't work great, but it sure does shoot great. For 150 grain bullets out of a .30-06 or .308 either one, it's hard to beat. That is the one drawback though. I think I'm going to make myself a dipper that dips about a half grain short, then I'll trickle up to my desired load. That should fix it.
