Reloading 7mm PRC

RL 25, RL 26, H1000 are all I can find info for......no reference to N's

Earlier in this thread I shared some info on N570 with 184 Berger's if you're interested in something similar…for me it is more consistently accurate with higher velocities than H1000.

I've also used H4831sc with some 160cx bullets but thw H1000 performed better there

If you're looking for velocity, ramshot lrt is what's working for me in 175 class bullets. Hitting over 3000+ fps out of a 22" barrel with no ill effects in 90 degree temperatures

I'm ready to shoot mine when temps moderate somewhat.
It's been humid and scorching here.
May tighten things up a tad. I've got about 325 shots through it so it's loose…

This is direct from Berger.
Not sure what bullet you wanted though but here's a start

I need a quickload chart for 160 noslers.
might play with AB's and BT's
I'm thinking Berger might not be the one to ax about that

Maybe your way more technical than myself but this is what I would use for 160 gr bullets.

570 will work, but 560 has been the ticket in the 7 prc. We have done loads for 10 7prc's in the last 2 months. We tested 8 powders in 2 guns. N560 was the winner for both speed and accuracy. The next closest was 4831sc. 570 and rl26 both pressured out on the 180 eldm at 40 fps slower. 560 worked the same with the 190 atip.

That's interesting that H4831sc was second in velocity for you. I've ran 3 powders in the 7prc now. H4831sc was way slower than H1000 and H1000 was around 70fps slower than the N570 for me. And I feel like I could push the 570 further while the H1000 was right on the edge of pressure.

This is with 180 class Berger's
 
My testing duplicates Bennies, h4831 showed good accuracy potential if you like .308 velocity. Ramshot lrt and n570 are in the same burn rate area, velocity with lrt was stellar in my rifle. What I see proves the point that all rifles and barrels in the same cartridge behave differently
