Hi everyone, I'm wanting to build a custom rifle, and prefer a 7 mm as I already have a 300 RUM. My ideal rifle would shoot either the 168 grain cutting edge MTH OR a 180 grain berger close to 2900/3000 out of a barrel no longer than 24 inches, preferably as short as 22. My goal is an elk capable rifle that can reach a max distance of 600 yards, but able to shoot targets to 1k. Will a 7 wsm accomplish this? Should I be looking at a 7/300 win mag? I'll be shooting suppressed to help reduce recoil, so what cartridges should I be looking at if I want to stay away from hard kicking/barrel burning cartridges?
