Muzzle velocity Differences between bolt release and cycled round??
#2
1 round vs a second is not the way to find or settle on MV. Need to run some groups, 4-5 rounds, several times and compute averages as well as SD's, then you can work with what it's shooting whether long or short range.
Your avg could be 2517-ish so 18 high, 17 low wouldn't deviate that much at distance... esp since you don't really know what the MV will be for a given round... that's where avg and SD come into play to give you details you can use.

Personally I like SD's in the single digits, ES in the teens, but elsewhere there is a good discussion that even a 20-ish SD can shoot accurately at distance... this confirmed by Klem who is a competition LR shooter...
