my vote is a 22-250....you can find a new m700 SPS varmint for 500 give or take...
everyone i know with one LOVES it...they are shooters out of the box with good glass....ive fired multiple groups under an inch at 100yds and many under 2" at 200yds...thats factory ammo and factory rifle...handloads im betting i can tighten them up farther...and a trigger job it'll shoot better...
everyone i know that has one loves theirs and all say the same for accuracy..
ive killed groundhogs at 350 with it...could go farther..just gotta find some longer fields!
