    It's normal factory ammo? If so, it's's what the gun was made to shoot.

    Well depends on how old. While it's certainly safe to use old or new blackpowder loads, the clean up is a mess. But stick to smokeless powder, and unless it's a reload some idiot decided to hotrod, you shouldn't have any issues. Although, you might want to stick to jacketed stuff for a bit to smooth out the barrel some.

  4. I shot SASS with mine it's a .45LC and never had a problem.
    Factory loads are mild for a Marlin, they are tough rifles,
    USA made of good strong steel.
    I never shot black powder in mine, but did shoot many
    reloads that I did in 225gr. and 250gr. lead.
    Excellent rifle. No worries.

    Your Marlin will handle every thing except the extreme Ruger only loads just fine! If they are factory loads -not a problem!!! Might want to stare clear of the Buffalo Bore loads! I broke my Win '94 with some pretty extreme Ruger only loads! The '94 action does has it's limts I generally keep my loads under 30000 PSI range(1600-1700 fps)! That is more then enough for 90% of the hunting I do with it!:supergrin:
