What would you say the best grain is for optimum results?
You loading yourself or buying factory ammo? You might be able to do some 40gr Varmit Grenades to some of the 68gr Hornady BTHPs. Maybe even the Hornady 75s. A fair amount of it has to do with velocity and how long the bullet is, not necessarily the weight. The M856 tracer round requires a 1/7 twist and it is only about 64grs but it's significantly longer than even the 77gr SMK.
Are you looking to just shoot groups at 100 yards or go longer range?
In for answer.
Factory ammo. For the most part it will be groups ~ 100 yrds or less, but plan on taking it maybe up to 200-300 tops.
I've had good groups with PMC bronze at 100 yards. It's a couple hundred feet per second slower than milspec .223 but it's a little more consistent in my opinion. Milspec ammo generally isn't as accurate because they are close to max powder charges, there are some exceptions though.
Back Hills makes good stuff, as does Hornady, though they can be pretty spending. If you're looking to really get into longer range shooting, a reloading press is a great investment.
