Hey dickcorn I looked up your rifle's serial number in the Colt database.
Says your rifle was made in 1891.
From Wiki..."The medium-frame Lightning was manufactured between 1884 and 1904. It was the first slide-action rifle offered by Colt.
Colt records indicate 89,777 were produced, in calibers .32-20, .38-40, and .44-40 as a companion arm to the Colt Single Action Army revolver"...
I'm seeing .32-20 Winchester centerfire ammo available through companies like Black Hills, Selway Armory and Ammotogo.
If you buy any I would stick to a low velocity round that has a flat nosed bullet (due to the stacking of the tubular magazine). The High Velocity 80 grain ammo that you may see available is loaded too hot for some older firearms.
