[QUOTE="ballisticxlr, post: 1706203, member: 82022"] I used 39.5 grains of RE23 for fire forming with 108gr ELD's. Could do a hotter load but there was no need to to get good forming and the cooler load would not be as aggressive on the brand new throat. Both the fire forming load and the final load seemed to like Winchester primers. Since I was starting with factory new brass there weren't a lot of options for how so I relied on the zero headspace setting to keep things lined up. Zero issues with that method. I used the first 250 shots doing fire forming but it was accurate enough that I shot most of those loads in matches. Did pretty well. Once all the brass was formed I jumped right up to development of full power loads and found the 45.5 load very quickly. [/QUOTE]
