[QUOTE="FURMAN, post: 1768062, member: 26535"] You can find the load(node) with new brass. Sometimes you will need to back the load off a little to get back to the velocity node sometimes you will need no change. I can't see the point in wasting components and barrel life. My new 6.5 PRC needed no load adjustment from new to once fired ADG. My newest 30 Nosler I had to back off .7 grains to get back to the accuracy. Every barrel I have every had also speeds up somewhere between 75 and 150 rounds. It speeds up anywhere form ~50fps to ~100 and when that happens I have always just backed the powder charge back off to the velocity the bullet was accurate at and I am done. My 6.5 PRC sped up ~70fps. My newest nosler was ~60fps. Between going from new brass and once fired and the barrel speed up on my nosler my final load ended up 2 grains lower than the original. Both were under .5 moa out to 1k with <20fps es and single digit sd.I could not disagree more with a dedicated fire form regimen with a non improved cartridge but you do need more data to make it work. There is a lot you can learn about your rifle and the load in the first 100 rounds. Also the lack of full length sizing every time just puts one more inconsistency in your process that makes no sense. Full length every time with a minimal shoulder bump so you have the same brass every time. [/QUOTE]
