Soil Swift makes a 55grn in their Trophy Bonded Bearclaw that performs GREAT in my 22/250 (but it is a 1:12" Savage). I haven't reloaded for this gun, just got them in Federal Premium Vital Shock. It will shoot through a deer inside of 100yds and should do ok from your gun (assuming you don't try to drive it at max speed).

Just a thought,
