I wonder where the OP went off to? If he wants a target rifle AND a hunting rifle, I'd like to see more info from him on what he was looking for - i.e. custom or factory rifle and how many rounds he'd be shooting at a time during his target shooting. None of the bigger 7mm's are target rifles without getting into some serious barrel heat and subsequent throat erosion.
ME? I'm happy with my 7mm, pushing a 175g SMK at 3495 fps from a 28" barrel @ 785' elevation. While I do shoot more steel than critters, it wasn't built to be a target rifle, and the gun sans scope and bipod tips the scale at 9 3/4#.
Oh, I forgot. If everyone is talking about powder efficiency, doesn't that relate back to powder cost per round to shoot? If that is true and I did my math correctly, I am using slightly less than $0.11 worth of powder per shot to get that velocity. That is without sales tax and shipping to put those numbers into perspecitve for everyone.
