7 PRC loads

[DTOM83]

I have a 7 PRC that I built with a 22” proof barrel that I’m wanting to load with 175 grain eldx and 195 grain Berger hunters. Has anyone got some recommendations on what to use for powder? What’s the most accurate powder to use for a 22” barrel that gives good velocity? Thank you for the feedback!

Thread '7mm PRC & N570'

Looking to see if anyone has any experience with this combo. Looking to add some speed over my H1000 load with 180 hybrids. I’ve done some looking around but haven’t seen a ton of people that are using this combo. Maybe there’s a reason?

Berger data shows it being nearly 100fps faster than H1000 but don’t want to burn up components if it’s not worth exploring.

Do you think the 570 is the best powder to use for those 195s even with a 22” barrel? Given the shorter barrel I’m not sure if there’s a more efficient powder to use. I’m new to reloading for rifle so I’m all ears if you want to impart some knowledge on me.

Anybody else have any experience with 7prc loading for a 22 inch barrel?

It's magic with 195's in big 7's if you can get the bullet boattail to the top of the neck/shoulder radius. I used it in a 20" 7STW with the same stellar results (81.3gr).
It'll eat the throat; buy a chamber chiller and shoot sparingly. If you'll shoot 500 rounds/year at the range, I'd pick a different powder or shoot a different rifle. That's the downside. I tried H1000 and 180 hybrids first and couldn't get results.

21” barrel, Bartlein 8 twist
66.0 N560, ADG brass, F215M, 3.28” COAL, 175 elite hunter - 2,880 fps.
Same load with 168 ABLR got me about 2,910

I have 2-rifles I have been load testing, the Springfield loves 65 grs of H1000 with the 175 and the Bergara likes a little more spice or 70 grs. Both single digit SD. This is a 4-shot group at 100. I had to play with the seating depth, seems they like jump.
