I also bought a box of these for this 300WM. I am not going to try to run them out to the book max of 3700fps though. I am asking to see if anyone has noticed/chosen any powder/load that seemed to give the best accuracy, say, from 3200 to 3500? I figure, hey, I shot the 240W & 257WM and 338 RUM all to 3500, so why not? Of course, I am still in awe of how flat the old SA 6.5/284/120nbt shot at 3200! Again, I just want to demolish coyotes/varmints w/o a ricochet harming John Dutton's Prize Bull! ( I used to say Farmer Dan, but this IS the West and since John Dutton ( Yellowstone) is the NEW J.R. Ewing...hey, he might be taking over this part of Utah!, I gotta be careful!!!
