Rocky and the 256 Win Mag

[RugerNo3]

I've read your article on the 256Win out of the Contender. I'm gathering up info to reload the 256 for the Marlin 62. I'm curious if you have notes on the Hornady 75 gr loading for COL in your load data. I have Re7 and 2400 powder, but would like to use the 75gr load to feed from the magazine if feasible and all else considered. I remember the fanfare at the introduction of this long lost round, but the inattention it received from varmint hunters led to its demise. I have some original once fired brass to work with, but no dies at this point. Thanks
