Sometime back I picked up a replica 1863 Springfield .58 cal. I'm mostly a flintlock shooter and after a single trip to the range the capgun got hung on the rack and that's where it remained except for a periodic wipedown with an oily rag and and an oily patch down the bore. This morning my foggy old brain took note of an oddity. The rifling depth at the muzzle is very shallow and gets deeper the further down the bore you go. In other words, tapered rifling. I've never seen that on a repro. I'm hoping someone can solve the mystery of who made this rifle. The lock is marked Amoskeag Manf. Co. with Manchester, NH under it and 1863 on the tail. No other makers mark (Zoli,etc) and no "black powder only" warning. Any ideas, folks?
