Pardon ignorance of 6.5 Grendel performance - newbie. I have not purchased a barrel yet, but am itching to. If I choose 16" carbine 1st, what is the anticipated velocity loss vs what most ammo advertises, which I assume is for 24" barrels? (I know there are lots of variables - just need a rough rule of thumb, maybe?) Any info greatly appreciated.
