Any case, any primer I don't size the case if fired in my Marlin just a light bell at the mouth. 60 grains of most any BP 2FG a 30 vege card over the powder, no drop tube, tap the rim of the case to settle the powder put the card in and 1/4 inch compression set the bullet and crimp. It's pretty tough to get 70 grains in a case but Winchester cases come closest and I can get 65 grains in those. I'm going to work up a duplex load to help the burn. I cast my own 405's with a Lee and soft lead then lube size in a Lyman sizer at .458 and use a slightly altered NRA 50-50 with Bore Butter and or bees wax, depends on how hard or soft I want it. Shoots good. I would like to try Swiss one of these days.
