New here, but reloading for a while. Just did some preliminary testing of the McGowen 24" with Barnes 105gr Match Burners over 28.3/28.6(2780fps avg/28.9 gr(2813fps avg) of LVR. Each grouped rather well, but was not concerned as this was for testing was for low SD with the last two being single digits. Now comes the seating depth(these were .015" off the lands) to get the groups as small as possible. What kind of velocities are y'all seeing with 105s? Just curious. Have a great safe day out there.
