A Remington 700 SPS Varmint in .22-250 Rem. Would be hard to beat
unless you can find one of the Varmint synthetic models. Put a Leupold
6-18 x a.o. or 6.5-20x a.o. scope on it with Leupold rings & base and you will have the best rig there is. One other BIG advantage to .22-250
is it is NOT .223 so ammo is not a problem.
