300 PRC loads?

[chromatica]

I am planning loads for a 300 PRC build. Does anyone have some good recipes for 220 gr SMK or A-tip 230? The powders I am seeing for this are H4831, RL-26 and IMR-8133. Is one of these more accurate than the others? My preliminary twist rate is 1:8.5.

My buddy has 300prc with savage action, shilen 8 twist bbl, fat bastard brake,shooting peterson brass, and berger EOL Elite Hunter 245gr g7 0.413 bullets. Federal match primers gave him under 5 sd. H1000 or Retumbo powder. He sent shilen dummy rounds for custom throating. Three of us shot it at steel buffalo at 1680yds. 20 for 20 center hits by the 3 of us. Tailwind that day so aimed at nose for center hits. Good luck with your build.

No experience with anything heavier than 225 ELDms. I've settled on the Berger 215. Just got some of the new 220s to try at some point. Hornady brass if you prep and sort it is holding up fine for me.
(Peterson does NOT make brass yet)
I've tried Retumbo, H-1000, and Reloader 26.
26 gives me the best accuracy with the 215s
Just touching 3000fps. 9twist 28",Kelbly. 225 ELDs shot pretty good but some question as to weather they made it all the way downrange made me give up.
