Curious if there is a consensus on a preferred powder for the 7 PRC and heavy bullets yet? I've seen people say velocity is good with N565, but accuracy isn't as good as some others. H1K isn't as fast but slightly more accurate. I ask since powder is so tough to find I'd like to stock up when I find it. I've got brass on backorder and have some parts for my build on order, so I'm really needing to settle on a powder and bullet at this point so I can stock up.

There’s an article in the 2023 Hodgdon’s manual. Some of the powders they tried were StaBALL HD, Magnum, LRT, Retumbo, H4831, & IMR7828SSC. Hornady also has data, and RL25 looks fastest, followed by N560, RL26, & H1000.

Lots of good powders between 565, 570 (24"+ barrel), staball HD, retumbo, 26, H1k.

If I couldn't shoot a few different and had to stock up I'd probably lean towards H1k. It's the H4350 in the bigger stuff. Temp stable and consistent even giving up 50fps. Good luck

Tagging in looking for N560 or N565 loads with Berger 180 Hybrid

I’m gonna use n570 and 195’s.
Honestly I'd like to use the 195s, but I've heard some bad reviews. I can't figure out if it's a velocity thing or what. But it makes me nervous to use them.

N568 is a turd! N570 is the powder if you are shooting anything heavy for caliber.
So n570 or H1K for a 7 PRC with a 22 inch barrel shooting either 180 or 195s? I'm thinking I'll have a +p too if it makes a difference...

Jake(UM) and I are building two 7 PRC +Ps to shoot in the Nightforce ELR Match in June.
I'll be anxiously awaiting a podcast on that. I guess maybe at this point I'll hope to stumble into n570, stock up on that, and then hope it works well for me. Worst case scenario I could use it for my 300 rum.
