Dreaming of a new rifle for next year. Not sure on the caliber, considering an STW for elk up to 500'ish. I'd like something light enough for a possible back-country hunt and after many hunts with my heavy varmint 22-250 I don't want another heavy target rifle. I love prairie dog shooting and would like to use whatever I get along with my 22-250 for this. But do the STW's burn up barrels fast? I'm liking the STW because there is factory ammo available if need be and the thing seems to be a laser! gun) Seems like the 300 RUM is very popular here in Montana but I'm a deer hunter first and only hunt elk because that EHD took out my deer herd. So I'd hate to shoot a deer with a RUM. As far as rifles go who's chambering a decent priced STW? I could probably save $2500 for the whole scope rifle package. Probably spend a grandish on the rifle then $1500 on the scope. How are Christensen rifles? Any suggestions on a good rifle in STW for around a grand? Can I buy a use 7mm Rem Mag and just have it rechambered? How much would that cost?
