Yes of corse & it will not harm a thing.
My pet load for shot in my 1860 or my 1858 is:
15gr. FFFG Goex.
piece of cereal box for over powder wad.
15gr. #9 or #7 lead shot.
piece of cereal box for over shot wad.
compressed melt candle wax over the wad to help it stay put.
Cap & it's ready for some Snakes up to 5 yards.
20 years ago I was able to find lead BB's & it was a good close range squirel load.
