Been working on a load for the good old Carbine.
Slugged and found it shoots best with .310 boolets.
Lyman 311359. IMR4227.
When I full length resize the shells, and reload, there is a step where the boolet seats in the shell.
I full length size for all semi autos I have.
This last reload I decided to only resize enough to hold the boolet.
Will try it this Sunday.
Just trying to get the last bit of accuracy out of it.
Shoots great at 50yds, expect it to do better at 100yds.
I've tried Blue dot, Win296, Unique,.
