I picked up 2 pounds of H4198 to try in my 45-70 Marlin XLR with Hornady 350 gr JFP bullets. The Hornady #7 manual lists max load at 45.3 gr while the Hodgdon 2007 and 2008 manual lists start load at 48.5 and max at 54 gr? I have triple checked and I am quoting data for lever action rifles for both. Any idea on why the big difference? The Hodgdon max load lists 54 gr at 39,300 CUP. Was wondering if anyone else has used this powder/bullet combo and what loads they have tried. The load I am looking to work up will be for non-dangerous lower 48 big game. I am thinking the Hornady 350 gr JFP interlock going maybe 2200fps would be deadly on anything up to moose with plenty of penetration? Anyone care to offer oppinions?
