300PRC Reloading

[therynb]

Hey guys and gals, I’m looking to start reloading rounds for my 300prc and I’m hoping to hear what recipes are working for you?
I’ve currently got Retumbo powder and 212 grain projectiles.

I’d like to stick with Retumbo as I have the best access to it but if you are having success with other powder or other projectiles I am all ears!

For reference I’m shooting a Browning X bolt max long range with the stock brake.

Thanks in advance! shoot straight.

I don't use Retumbo in mine, I've been using N570 with 225 eldms (Lapua brass).
Went up to 82gr of N570 before seeing pressure (slight ejector shine). Avg velocity over 5 rounds at 82gr was 2960 fps out of a 26" Bergara HMR.
OCW work came up with a nice node centered at 81.0gr of N570. Avg velocity is 2920 fps at that powder charge.
I've picked up a bunch of 215 and 230 Berger hybrids that I hope to test soon. I've been seeing low SD/ES with non-magnum primers but at some point I may test out the 250 and 215M primers that I have on hand.
Hope this helps.

I use Retumbo. Fed215M primers, and Hornady 212 grain ELDX's in my 22" barrelled Christensen's Arms with good velocity and great accuracy. I am .8 of a grain below book max.
