I just bought an 1896 Krag carbine, made in 1897. The salesman said it's not an antique because it isn't black powder. I said it was made pre-1898. He said it shoots self contained cartridges. I said the ammo is not readily available (sure, you can find some).
Why is it important? Because in MA, you have to register all guns purchased, even rifles, except for antiques.
Any opinions? I say it's an antique.
