Another thing that might make it a bit easier to hold is shooting 60 grains of T7, I do not think you could hunt big game with that load,
It would likely do the job with good shot placement at reasonable ranges. I'm sure a lot of deer were killed back in the late 18th. centruy with the old 45-60 Winchester. But I believe that round used a heavier lead bullet - something like 300 grains - over a 60 grain charge of black powder. If you put a Lee REAL or Hornady Great Plains over that light charge of T7 you would be good to go.
Just enjoy the moment!
That, my friend, is the secret to a good life.
