[QUOTE="mw185, post: 245562, member: 7912"] My reason for the question is I am working up load for new 300wm(26" lilja , mauser action) .Worked up to max load (nosler data 200accubond) with R22 and H4831sc. Average vel(5 shot) with 72.5 R22 was 2836, for 4831 at 71.5 was 2808. as data said velocities should have been around 2960 and 2910 respectively(test barrel was 2" shorter at 24").Groups were better with the 4831 so I worked up to 73.5 grns with avg vel of 2844. I would love to get around 2900 but being a general follower of the experiences of those before me I question whether to pursue 2900. My hopeful theory was increasing case capacity for powder by seating out to .020 off lands at oal of 3.573 and neck sizing only was the reason for increased powder. What would you do? [/QUOTE]
