I am having my 300 wsm tikka t3 rebarreled and am undecided between the 7mm/300 wsm and the 7mm SAUM. I think both have strenghts and weakness. I will be hunting in the mountains of eastern washington for mule deer and shots can be long est 700+, though I'm not ready for shots that long yet. SO primary use of gun will be mule deer eastern wa. secondly will be black bear hunting in western wa, shots typically much closer as the forests are heavy, and third occasional elk hunt eastern wa, typically bow hunt for elk though. I'm looking to change rounds because I would prefer less recoil so I can enjoy practicing shooting more and improve the ballistics of the 7mm. reasons for the 7mm saum. It comes within 100 fps of the 7mm/300 wsm but with 8-10% less power. If anything should happen to pet load while on trip although hard to find factory ammo available. With the 8-10% less powder also comes less recoil. reasons for the 7/300 wsm able to push the bullet alittle faster but at the cost of more reciol. The reason for no factory 7 wsm is because case forming would be more difficult when trying to use high quality brass from norma or nosler (would require fire forming), also the neck is shorter than the 7/300 wsm. This will on a long action so I can seat the bullet out farther than if it were limited to a short action. Thanks for any input.
