First of all you have a gun I have great interest in owning someday soon, so I am a bit (a lot) envious
I would set aside the 'hand loaded rounds' and perhaps pull one apart and weigh a load and if you have any Bullseye on hand compare the power in looks. I am not thinking that a 2.7 load of Bullseye should give much recoil at all but I have not shot one of these guns yet.
