I have found the 160 ftx marlin express with lever lotion powder exhibits a maintanence of higher velocities with shorter barrels. 20 inch or 22 inch. Using a 24 inch barrel the h 4895 with 165 grain speer or Sierra boat tail catches up to the ftx somewhat. I would suggest using the 308 marlin express load data if you want to try lever lotion and ftx bullets. I am still on the road not near my man cave library data base.
