[QUOTE="eshorebwhntr, post: 791038, member: 17112"] I thought of just running a straight load in this round and not fooling with the fire forming but I didn't based on what a friend of mine told me. He has a 30 Hart which is a wildcat based off of the 300 weatherby. His accuracy suffered substantially when running 300 weatherby brass through that chamber and then had to rework another load once all the brass was formed to 30 Hart. I already basically have a load that works and a 300 HH will not hold that much powder. The new fire formed cases will. Jury is still out on if they will be as accurate as the load was in new factory R-P cases. Also, I was probably getting loose pockets on the 4x firing because of my bullet/seating depth. I was running 180 berger VLD's .006 into the lands. I've now switched to 180 Hybrids which by everyones testimony so far shoot just as good .010 jammed as they do .060 jump. Again, I'll have to see for myself. Just wanted to clear up, I don't do all the steps I showed pics for (ie 2.5, then 4.5, then 6.0). I anneal, size, charge to 6.0gr, fill, and shoot. I just wanted to show everyone what I went through and why I decided on my recipe so they could feel safe if they wanted to attempt it. Hope to post some accuracy/velo results soon when I get time to load the brass I've made and get to the range with em. [/QUOTE]
