I've often wondered if there was enough recoil to worry about a 75 grain HP bullet in the tube magazine to set off the cartridge ahead of it.
But, I have only used cast, 60 grain Hornady FP, 60 grain factory Winchester & 75 grain Speer FP in my lever gun. I used to have a contender with octagon barrel in 256, I used 75 grain HP's in that.

I prefer classic.
