Home Forums Lever Action Central Big Bore Levers Marlin 45-70 Barnes X Load Data??

Nephew just got a 45.70 for Christmas. I've never loaded this round. The closest I've come is 50 beowulf.

They ordered some dies and 250?? grain X bullets for it.

Any input to load data or pertinent info on the gun(Marlin) and loading would be appreciated.

Thanks, Jeff
