If you are going to use the rifle for your one and only do it all hunting rifle,and then hand it down,be prepared to have it rebarreled a few times.To really get to know the trajectory and wind drift,and to develop and maintain the skills necessary to realize the advantage that the 7mmRUM provides over cartridges such as the 7mm remmag,you will need to do a lot of shooting,likely a couple of hundred rounds or more per year.Even with proper care,7mmRUM barrels usually suffer enough throat erosion within 1000 to 1500 rounds to result in accuracy fading to where the barrel should be replaced.For a two or three boxes of ammunition per year shooter,the 7mmremmag is a far more practical choice.I base my opinions on actually having owned three 7mmstws,one 7mmRUM,and two 300RUMs,and having shot out barrels on some of these rifles.
