N-165 is yes but 565 is not. I should have been more specific.N-165 is one of the coolest burning powders available, along with N-160. I load N-160 in the 7-6.5 PRC and the barrel on my rifle has ~920 rounds on it. I scoped it after the last cleaning, and I saw the barest hint of fire cracking just before the lands. There's a bunch of life left in this barrel. My previous barrel shot better with RL-23, and the fire cracking was quite apparent at a similar round count, and it was done at 1,400 rounds.
The 500-series powders are all double-base, containing nitroglycerin. They can't help but run hotter, and some more than others from what I hear.N-165 is yes but 565 is not. I should have been more specific.
Even so, I've noticed less barrel heat from N555 than RL23 or H4831, in the same barrel and cartridge.The 500-series powders are all double-base, containing nitroglycerin. They can't help but run hotter, and some more than others from what I hear.
A fella in our club got 900 rounds with his 6.5 PRCF Class rifles get shot hard. 6.5 Creeds go 1500ish. I would expect the PRC to live 900-1300.
I’d rather not shoot anything above 20ftlbs of recoil due to shoulder surgery.
I run the numbers and it seems at certain velocity it can be on par with .284 win.
I am planning to load 144gr bergers over N565/N165.
