I am looking for some ammo to really see what the accuracy of my SPRish build is. Barrel is an 18" Noveske in a Vltor VIS.

I have been using Prvi 75gr. BTHP rounds. I have had what I consider now a fluke .63 moa 5 shot group with this ammo. The last couple sessions I was getting pretty consistent 2 moa groups. This is fun for banging steel, but in 100yard groups leaves something to be desired.

I see many companies load the SMK, but who does it best? Is there also a different bullet I should look at?

This is going to be for shooting 100 yard groups on paper.

Price doesn't really matter, though a good value always makes me happy.
