[QUOTE="Matt Wolf, post: 1495644, member: 102893"] I've just put together a hunting rifle on a R700, 1-8.5" brux 2B @22", chambered with a .296 neck/ 0.081 freebore. For now I'm running 140 amax, and cases formed from R-P .300. I've been squirrelling away parts and components for this project for quite some time, so when a buddy mentioned that he had 16 lbs of H1000 that he wasn't using, I grabbed it. For thre initial range session, I loaded a a few rounds with 58 grains for zeroing, and a ladder from 57.5-61.5 in 0.5 gr increments, just to get a base idea of charge/velocity. Velocities were measured with Labradar. Now, I know the barrel is brand new, and it should speed up, but 61.5 grains of H1000 only gave me 2780. Pressure was a non-issue, but I'm wondering if older H1000 is slower than the current formulation? My lot is at least 11years old. It has been stored correctly, but it's old all the same.

I know the 6.5 4s was develop to run a 140 at good velocity, without pushing overly hard, with the idea of reasonable barrel life, and H1000 is preffered because of the burn temp, but since this is a hunting rifle, and barrels are just a consumable, should I just move on to R26 and be done with it?
