Finally got the new 300 PRC and shot a few Hornady factory 212 ELD-X through it to break in. Shot those around 1/2" at 100 but I now have some Lapua brass and can't wait to see what reloads will do. I would appreciate some recommendations for starting loads. I only have H1000, CCI 250 primers and the following bullets: 212 ELD-X, 225 ELD-M, and 215 Hybrids. I have trimmed the brass, run through Redding Type S bushing die and primed. The necks on the brass were extremely tight. Had to lube inside necks to (easily) run through carbide expander ball. Also noted that primers seated without much resistance. Anyway, please give me your thoughts on starting loads.
