23.0grs of IMR4895 in RP brass is running just over 1/2" for 3 shots - 5 different 3 shot groups. 1 9 shot group gave me 1.4" with 2 yanks of the trigger that I knew I yanked, the other 7 shots were just a shade under 3/4".
24.0grs was 1"
24.5grs was over 1" and was so compressed it creased the nose of the bullet.
23.0grs isn't very fast I'm sure since I've not chrono'd it yet but I can deal with that kind of accuracy for a 400yd steel dinger.
This rifle never shoots well on upper charges for some reason.
Chrono'd 23.0grs IMR-4895 and the 68 BTHP Match - 2688fps
