i can borrow a magneto speed to also try and see if im still getting the same readings
one thing i just though of is ive set up all the balistics data in my atn scope including bullet speed and so far the ballistics calcs in the scope have been accurate out to 1150 yards so im thinking if my chrono was that far off id know at that range
What was the length to contact of lands for your handloads? What's the jump?
Just to rule out jamming and short throat.
Not saying your loads aren't safe in your rifle. Just they aren't inline with typically seen velocity's for that length barrel with any ammo, factory are handloads.
