Your throat length and seating depth will influence the choices.

If you're looking for generic information, call Berger as they have information available.

N570. I ran that setup for a while and it absolutely hammered.

N565 / N568 / H1000 / Retumbo

 

[TopPin]

Personally I prefer H1000, then Retumbo. N570 is a good powder, it's like rolling an untuned Deisel blowing coal down your barrel, and you can spend the next 2 days scrubbing the barrel and cut about 300 rounds off of barrel life. There has also been a lot of very good results with R33. I personally prefer temp stable powders.

I have a 300 Rum in a 26 " OMR Carbon 1 /9 twist Remage and it settled in at 3010 ft.per.sec with the 245 gr berger and Nv570.
Cant go wrong with a Rum !

N570 will get you the best velocity, H1000 will get the best barrel life but will be noticeably slower.

Barrels are cheap……

N-570. OR RETUMBO

N570 did well in my 8tw with the 245 and the 215. It wasn't as fast as @Rum Man , because I am scared...

That said, at about 650 rounds down the tube, it has started to get loose.

Howdy I did load development yesterday for one of my 300 Rum.
But it was with 215 Hybrid using N-570.
95grs was my max at 3307fps.
Found a good node between 93 and 93.5
I went with 93.3 all 3 areas produced 3220fps with. 2sd. The picture below was 12 shots at 100yds shooting the 3 different loads. C.o.a.l 3.855, 28" barrel. 4th firing on rem annealed brass.
Fed215M. Now I need to try it at 300 & 500yds. I started using 570 a couple years ago, not looking back.
Retumbo what I did use.
