a few years ago I bought an Alex Henry hammer falling block rifle. It's a small frame rook rifle that was bored out to .410. I've had it at the gunsmiths for awhile now and he's finally getting around to making a new rifle barrel to match the old one. He asked me if I was sure that it was chambered for the .350 2 1/4" BPE. I showed him Wal Winfer's book page 60 the first paragraph. He doesn't believe that the small frame and barrel can take it. Was this a misprint? It does seem like an awfully small rifle for the cartridge.
