44gr RL-17 doesn't fill the case to the base. Oh well, its a start load. Blow the case to AI anyway.H4350 or XMR4350 - nice case fill, temp. change stable & accurate. I shoot rodents with a .243W using H4350 & 87 VMax bullets & sometimes temps are over 90 deg. F. Nice 400 yard performance with velocities at about 3200 fps.
