30 cal bullets

unspellable · 07-19-2002, 01:17 AM

I have a friend who does a lot of bullet casting. (Sells 'em in several stores in the area.) He is not too fond of the Lee molds. Favours Lyman or RCBS.

I haven't done very much casting myself.

In general, you want to run them through a sizing die after casting. Slug your barrel, round up to the nearest thousandth, and that's your sizing die. For example, a 0.3105 groove diameter calls for a 0.311 sizing die. If the barrel ie 0.3100 go for the 0.311 sizing die. A cast bullet wants to be a tad oversized. This may or may not effect the size of the expander plug in your loading dies.
