[QUOTE="backwoods83, post: 459865, member: 29890"] long time long ranger said that one well, a 257 wby with a medium contour barrel and decent optics, 8-9 pounds, mine is a little over 9, but it feels like my 243, the first deer I took with that rifle was 268yrds and i was sighted 1" high at 100, 100grn hornady spire, that thing folded up like a book. They are quite a bit of an overbore but they are not that hard on barrels unless you get um heated, dont shoot anymore than 3-4 rounds without any cool down, they will last well beyond 1000 rounds if you do that. If not a regular 7mm rem mag with a 10 twist is all you will ever need for anything under 170 grains. comparitively the 162 grn sst interlock will give you the most terminal energy with its .550 bc it will still have about 1015ftlbs at 900yrds with 3000fps mv.
