try some of the faster powders, like aa2015, rl-7, and imr4198.
the 87gr v-max has a balistic coeff. of .400, and is what i'm trying in mine every chance i get.
about 1 1/2" at 100 is what i've got with 44.0gr of imr4350. i'm now convinced i can do better with those powders previosly mentioned. all the while getting less recoil/muzzle blast.
scope.......get a 3x12 burris and set on top that thing! base......i have a virgin valley weaver type on my .243, with 3 burris signature zee rings holding the scope. this is by far my mostest...
... favorite base/ring/scope setup so far. it ain't cheap, but it's good!
a standard weaver base will work fine, and would save a few bucks, but the vvcg model is.... solid steel.....stout....and really good lookin, imo.
my other encore(7-08, and 6br) have burris dual dovetail bases, with 2 signature rings.
i also like the 3 ring redfield mount/2x7 burris scope really well on my 30-30AI.
heck, i guess i'm easy to please.
plus, i havn't had any trouble with any of these yet.
