7 PRC best powder choice w/153 HHT

Juan Deere · Sep 8, 2024

I'm having a rifle rebarrelled to 7mm PRC that will be 22" in length. I plan on shooting the Hammer 153gr HHT bullets and was wondering what type of powder you guys have had success with this bullet/length combination. Thanks for your time!

Tagging in. Same set up. Was thinking RL26 interested to hear what others suggest.

Not the same bullet, but I have used N565 in my 22" 7 PRC with a 160 mono and had great results. Two different 5 shot groups with the same exact same average velocity of 3179.6 and exact same sd of 2.6

I've tried 4831SC and N568, both will do very well, 2900 or so fps with 175 gr. Have been looking for 8lbs of H1000, but I don't really need it.

Good luck

Can you share what bullet and what velocity was achieved?

I had very poor velocity results with H4831 and 180 gr out of a 20" 7PRC. It just built pressure way early in load development. H1000 was just too slow of a burn rate. R26 did the trick with 175 ELDX at 2900.

I am still working on a load for my 7 PRC with the 153 HHT using H-4350 getting good results under .75 moa and a MV of about 3200. Still trying do dial it in a little more

You may not have been asking me, but I got 0.45" groups with 65.4 gr 4831SC and 162gr Eld-M with avg MV of 2936 from a 24" Proof bbl.

I've been running a similar load.
Peterson 7 PRC brass
162 ELD-M
69.0 H4831
Fed 210M
3,100fps in a 26" Bartlein carbon

FWIW - loads up to about 3,200 fps are doable

Can I ask your load details. What brass, charge weight and overall cartridge length. I just started break in on mine but once it speeds up gonna start load work with the 153HHTs. Thanks!
