Help with 7mm prc, Berger 190 lrht and RL23

[bryanfields]

Hi. I just picked up a Seekins Element in 7mm prc. Barrel has been trimmed to 18".
Was planning to try Rl23 along with a couple other powders with Berger 190lrht.
Berger does not have any data on this combo.
Checking here to see if anyone has tried this and has any advice.
Thanks!

Hornady has data on their 190 atip. Just follow that, start low and work up.

Make sure you have plenty of RL23. Enough for the life of the barrel.
Otherwise, switch to N565 or H1000. Stuff you will be able to get in the future.

RL23 might be a bit fast, but might work fine.

I use n570. It's great in the 7prc. Especially with heavy bullets

Email Berger and they will give you a call and give you the specs for that bullet. I shoot these over Retumbo in my 28 Nosler.
