Dave,
As mentioned by stick, really depends on what your definition of accuracy is.
Glass-bedding, free floating the barrel & doing a minor trigger tweak may be all that's necessary to get your rifle to shoot well under MOA with the right load. Might do it already. The right load combo is sometimes the only thing needed to make a rifle really shine.
Whole deal, if you're handy with tools, will cost about $25 & depending, about a week & that's for the glass to fully set up.
