Ammo choices - am I being dumb?
I have settled on only buying ammo that is 40gr "standard velocity" (i.e. around 1050 or so FPS).
The main reason are:
I don't want supersonic ammo for shooting at 100 - 200 yards because it's not as accurate.
Being subsonic, it works great when I put a can in front of it.
And, mainly, because I usually zero my scope at 50 yards and I'm thinking that pretty much anything from CCI SV up to Eley Match will be pretty close to my zero when they're all 40gr standard velocity.
So, I can plink and practice with cheap ammo and shoot match ammo when I'm doing something that merits the expense, and not have to be constantly re-zeroing my scope.
OTOH, I'm guessing that if I buy 36gr or 42gr ammo or ammo that is the really slow "quiet" stuff or anything supersonic, my scope will be off by a fair bit at 100 yards.
According to AB Quantum, the difference between 1050 FPS and 1250 FPS (both at 40gr) is a bit under 2" at 100 yards. That is more "off" than I want to be if I change ammo.
Is my logic here valid?
