The velocity seems to me to be about 100 fps low, and exbal probably proves it. If you can find someone who has an Oehler 33 or 35, shoot through it and see. Try the Lapua through it too. Remember that the muzzle velocity will be a little higher than instrumental velocity because of the distance to the screens. Not much though. I just use the instrumental velocity and don't try to correct to M/V.
If this load groups, extracts cleanly, and has a good standard deviation, there isn't anything wrong with it.
Good shooting, Tom
