6.5 PRC Loads
- Thread starter 357Max
- Start date
Alliant isn’t shipping to the US for the foreseeable future due to raw material shortages.
RL 15.5 has been fairly available lately & it works well in 308 with 169gr+ and 6.5 CM with 130gr.
For the PRC I’ve got a few pounds of the new Ramshot Grand inbound. Reports have been good for 6.5 & 7 PRC. I’ve seen +100-150fps more than Staball HD.
Meanwhile Vit N565 has been working well.
Barrel just hit 120 rounds & I’ve now got fire formed brass to work with. Fairly LT profile Carbon barrel and I’m pleased that it’s not really shifting as it heats up. Didn’t have any pressure signs on any of these. Not pushing it hard with the Virgin Brass.
How's temp stability of the 15.5 compare to 16? I use RL16 in another cartridge but it's getting spendy, phew
From my experience, 15.5 is very stable in a 6 Dasher. I've shot matches where it was 50 in the morning and 95 at the end of the match and I had maybe a few FPS difference at the end of the match. So the difference didn't matter. It is not like RL15 at all where in my 7.62x51 if I shoot my 118LR at 60F its 2660 FPS and at 95 it is 2740. 26" barrel.
Try 4831SC, I find it to be better in every way. I am getting similar velocities, great temp stability and excellent extreme spread.
Im also running shorter barrels and the N565 is super slow, I gave up on it right away when it was running CM speeds.
RL 26 is an excellent powder, for a variety of cartridges. It's gotten ridiculously expensive and almost unavailable.
The 6.5 CM gets the same velocity as the 6 .5 PRC with RL 26, And hybrid cases with good accuracy. And the AR 10 in 338 RCM with and 18" barrel does well with RL 26 and a 250 gr bullet, as does the 338 WM.
Here is RL 26 in 6.5 CM 150 gr SMK with hybrid 6.8X 51 reformed cases, in a factory 24" Ruger Precision Rifle.
I'm a big fan of RL 26 in quite a few cartridges, but can't get enough in a 308 Win case to beat out 6.5 Staball with heavy bullets, maybe the 250 Atip in long throat long action.

I’m shooting N565 with 156EOL in a 20” barrel. 58.5 grains = 2,825 fps.
N560 works great with lighter bullets.
Same rifle, 58.3 N560 with 140 elite got 2,980 fps
Is this a SA? How long you loading the 58.5 156eol load?
I was fire forming and breaking in barrel so I didn’t push the load to find pressure.
Yep. Used 58.3 N560 with a 140 elite hunter last fall, was 2,950 fps
Again, it worked in my rifle, others might might want to work up to that.
That consistent with the speeds I'm seeing with 56.5 gr of H4831SC. Seems to be about the peak of what's to be expected with a 20" barrel and 140 gr bullets.
