Rl 26 will more than likely work just fine. I'd bet you could find something with 4831 also but would be giving up some speed. I've only ran n-565 and Retumbo in mine. And with Retumbo it was only with un formed brass and I ran out of space. Es seemed pretty high as well but more and more, I think that mostly depends on the barrel. I heard some positives on n-570 but it'll take a long drop tube and a lot of patience to load each round. H-1000 has worked excellent for some so imr 7977 may also be an option.Alright, been reading through the 16 pages of this forum and I’ve heard good suggestions on powder but what’s the consensus? I’m at least a few months out from getting my rifle (wanting to use the Defiance anTi and deploying) so I’m really in no rush. I have on hand 4 lbs of RL26, 4 lbs of 4831sc, 2 lbs if imr4350 (and a bunch of others not listed but not fit for this round). My 270SS loves RL26 under 156 hammer hunters. I’m sure RL26 will work, but that leaves me with 4 rifles using the same pounder which is hard to find!
Went into my local shop last week and they were out of RL26 (first time they’ve been out!). They have H4350, N570, H1000, and IMR 7977. Should I pick up a couple pounds of one of these to use or just stick with RL26 and chance possibly running out?
I’m a hunter and not a competition shooter so my volume of shooting isn’t as high as most y’all. 4 lbs of 26 should last me ~2 years or so.
