I was recently in your shoes, sort of... Was looking for a new rifle that had a bit more performance than my .270win. Really struggled between a 7mm and a 300win mag. Ultimately went with the 300 win mag, in a Christensen Ridgeline. With the muzzle brake, it kicks far less than the .270, to the point where it's nearly not noticeable. The gun is legitimately fun to shoot 40+ rounds at the range. the 300 gives me the ability to sling a big heavy bullet a long way.
