boattail, been where you are at. I too am just getting started in this long range stuff. Got a lot of goood advice from this site.
I bought a Winchester Coyote in the 7mm WSM
and I really like it. I took it to a good smith and had a muzzle break put on (130.00) had it pillar bedded (90.00) and had the trigger reworked (45.00). It is shooting 1/4" at 100 yards using IMR4350 and the 162 gr AMAX. I couldn't ask for more for my first gun.
Godd optics is a key though. Leupould LR set me back almost as much as the gun reworked. But boy is it fun shooting.
Have fun with what you choose [img]images/icons/smile.gif[/img]
