Well, here I go again, with a load of questions.
I bought a RCBS 300 grain 45-70 bullet mold from Midway, and received it yesterday. This morning I cast about 250 slugs, and sized them and put on the gas checks. I'm going to pan lube them instead of using my Star sizer.
Well, one question I have is they weigh in at about 328 grain without the gas check. Why would that be? I didn't figure different alloys would give that much a variance in weight. I was using melted wheel weights.
The other question is the little amount of lead that "oozed" between the die halves when I was casting them. You can see it on the nose of the upper bullet in the picture I've attached:
I've always used Lyman molds in the past, and have never had that little "ooze" line in the nose of the bullet. I guess I could clean it off with my pocketknife if it would cause a problem. Is that common with RCBS molds though?
