If the workmen on the factory floor at Kynoch's paid any attention to the drawings they were meant to go by, you ought to find a 1 in 12 bullet measuring .400 plus or minus a half thou wrapped in 3 thou paper. Or if they were loading grease groove metal based, .410 plus or minus half. But the buggers were English, after all, so you never know what you'll find.
The last 450/400 3 1/4" that came by here shot a 255 grain .400 bullet patched like that with 110 grains of OE 1 1/2F like that's what it was made for. But it is a Fraser. There's no telling what one of those contraptions the bodgers in London put together will do, is there?
Thank you, Mike! I ordered two boxes of antique rounds. The first are paper patched BPE rounds, clearly what was shot out of the BPE guns. The other box has a label saying "KYNOCH .450/.400 Nitro Express Cartridges Case 3 1/4" For Black Powder Rifles" stamped "Metal Base"... These have no paper patch. Opening up one of each should be interesting, and hopefully not exciting. I know you will be interested.
