I am looking to build a rifle that will take deer and elk sized game at extended diatances. I have been looking into possibly building a 7mm stw with a 28 inch tube. While I like the .25 and .30 cal mags that I own, I am always looking for an excuse to buy something different. The 7stw or 7rum seem to be good choices. From what I have been reading, however, the 7rum burns bbls out somewhat quickly. I am sure that there are some that will argue that point, which is why I am asking for help/suggestions. Thanks in advance.
