Recorded velocity 3013fps Data velocity 3300fps

I appreciate that it's a different bullet that I have seated quite far out. 22inch barrel.

Questions. Would seating the bullet in further generate much more pressure/velocity?

Should I increase the charge beyond data to achieve something like 3300fps?

I have the same story going on with a 6.5 x 55.20inch barrel.
Also a 250savage that is recording velocities as expected.

Check what barrel length the load data you are using is for. Typically it is for a 24 Inch barrel.

Is it a new barrel? Some need a couple of hundred rounds through them and then get a velocity increase. And some manufacturers have slow barrels for some reason (looking at you Tikka)
