162 A-Max Norma brass, CCi mag primer and 72gns of ADI 2217. Ive got them seated to fit the mag which is a .052" jump! I tried seating them out to near touch 0.015 (which would mean single feed) but it shot worse. Fps is a touch under 3000fps.
I've got the same rifle as you and I'm on my last box of 162 amaxs which shoot 1/4 on a bad day.
Interested in what your load data is, powder/length to ogive etc
