You will spend a bunch of money rebarreling, dies, brass and likely won’t get the versatility you have now. If the gun is accurate, spend some money on a nice scope, reloading setup, do the trigger and be happy. The grass isn’t greener then a 7mm Rem Mag imo.
I have the same dilemma with my 7mm RM. Every once in a while I think I will turn it into a 300 WM or something but if you can’t justify buying the hunting rifle in the caliber you want to get to in the first place, rebarreling is not a better route to get there.
