Thanks to everyone. Seems nobody is really too surprised by the difference so I will try different types of ammo and go from there.
Along with what everyone else said, the published velocities on boxes of factory ammunition will seldom match the actual velocity out of your rifle.
Without chronographing the rounds out of your guns there?s no telling how far off the published velocities are.
BC and Velocity differences in the ammo, plus the differences in the barrels, etc. Not surprising at all.
I appreciate all the responses, very helpful being new at this. Thanks.
