Finally bought one. Now, I'm asking what some have used for powders in this fine caliber.
I have: H4831, MagPro, H4350
The previous owner used Hybrid 100V with good success with 162gr Amax.
I thought of trying, 100V, Winchester 780, R17 or R19(what the Hornady manual likes) or even the the new Alliant 4000MR.
I plan on finding a load with a 150gr or heavier bullet for hunting. I need to order some powder for other uses, just getting ideas to start with.
Thanks

I had broke the barrel in enough to get it to clean up pretty good in only 30 rounds, so I loaded 25 rounds, 5 each from 56.0 to 61.0 and I had already ran tests for pressure while I was breaking it in, and was able to get up to 62.0 with just a tiny hint of pressure signs.
Results are shown below, and I think I'll keep this one as it's shoots better than any factory rifle I've shot in a while.
It looks like the 61.0 load wants to go higher, but I have no need for speed so I'll recheck the 59.0, and tweak it from there.
Looks like a keeper. Which gun did you get? -- That's a good round that should be more popular than it is. Reminds me of my 280 Ackley Improved as far as performance goes & with 140 gr bullets in both is just about a ballistic twin to the Winchester 270 WSM.I've got a friend who has a Remington SS BDL sporter weight in 7mm SAUM and it shoots well too. I like it better than the 280 Ackley just because you don't have to screw around fire forming brass........good luck & keep us posted........best...............
Temblor,
It was a 700BDL S/S. I put it in a Laminated stock with pillars, and the barrel is fully floating, and don't seem to need any foreend pressure. Water capacity is close to the 280 AI.
