Thanks guys, all great observations. Anyone try R17 in your 300WSM?
64.5 gr's RL17 under a 180 Partition for 3,030 fps was my go-to 300 WSM load (another is 64.0 H4350 for 2,980).
As to lightweight 300 WSM's, I had several Kimber MT's. All-up with a 3-9 Leupold, Talley Lwt's, Unlce Mikes Mtn Sling and a full magazine, weight was 7lbs 4oz's. The Kimber 8400 Stock is the best I've ever used for recoil, but I found the no.1 barrel too light. If the Kimber had a no.2 contour it would be my ideal 300 WSM.
But I have no need for magnums on elk anymore and have gravitated to milder recoiling rifles. More fun to shoot, can be built lighter, and dead is dead.
