[QUOTE="AZHTR, post: 2220397, member: 105904"] I apologize in advance for the lengthy explanation! I’ve read EVERYTHING on LRH regarding 6.5 PRC loads, BUT I’m reloading for my friend’s 6.5 PRC (Christensen Arms) and have struggled helping him develop a good load. I tried talking him to a 7 MAG, but he had to go with the latest and greatest😳 Equipment - A&D scale, Wilson Bullet Seater, (borrowed some Lee Dies - Redding dies on order) 100 rounds down the tube so far COAL: 2.940 Brass: Nosler (blems) Bullet: Hornady 143 ELDX Primer: FED 215M (also tried WIN LRP - no difference) Powder: H1000 (55.0 to 57.0) no exceptional groups, developed pressure very early (~2880 FPS) Powder: IMR8133 (56.0 to 57.5) .75/1.0 MOA, but FPS ~2800 range, loaded hotter but developed heavy bolt lift Powder: IMR4831(47.5 to 49.5) at 49.0 shot 1/2” MOA ( AVG FPS @ 2841). Starting to develop heavy bolt lift Side note - I shot 3 rounds of factory ammo (.7 MOA) and shot 1 round for velocity (3010 FPS). Hornady Precision Hunter 143 ELDX. I thought I could get close to duplicating this, but so far it’s a no go. I’m sure I’m not the first to disassemble a factory load and find there is 54.84 to 54.86 of some type of powder, but it is definitely a mixture of powders. (Black powder with sprinkles of brown kernels, approx. 1 grain = .02) Opinions/suggestions Welcomed😀. Should I just tell my friend to shoot factory ammo? He said he can’t find any!
