Yea, I'm not sure what is going on with my Varget and pressure because a similar thing happened with a new jug on the 6BR with 30.0 gr which had been ok in the past. It will be interesting to see what happens with the RL15; according to Quick Load the max pressure is less than that for Varget to achieve the same velocity - the pressure profile through the barrel is different. During my initial ladder tests the recoil "felt" like this was the case, and I'm scaling up now to check seating depth and should have a more firm result soon.
