WolfKiller,
I asked my self this same question last year,except I wanted a light cary rifle for elk and moose,mid to long range 400 yds.And I went with the .300 WSM in the model 70 Super shadow,this a great pack all day rifle just under 7 lbs w/scope.I realy do like this little gun.I have several guns for just elk and what ever,I dearly love my .300 RUM don't get me wrong.If I was looking into get just a strictly deer/sheep rifle I would consider the same gun in .270 WSM.If I had my choice I think I would like Browning BLR in 7mm-08 Rem,these little guns are wonders of the world and fast handling.But I already have my sheep gun for my Big Horn tag I will draw this year(I hope).It's a Ruger No1 25-06 rem loaded with 100 gr Barnes Triple-Shoks.
Good luck trying to pick one,it almost nerve racking
