I'm starting a new adventure with a Marlin 1889 in 38-55 in very good condition. I have picked up a box of Winchester Legendary Frontiersmen factory ammo from a member here.
My question is if factory ammo is safe to shoot in this rifle. I will be reloading back to black powder pressure levels. I would prefer to shoot this ammo and then load back, but will break down for components if needed.
Any and all advice will be appreciated.
