Ron - missing the .577 Revolver was a mistake on my part.
On the .475x3-1/4", is that a straight or bottlenecked case? I’ve never seen one, which explains why it isn’t on the list. I’ll have to measure my .450 3-1/4" rounds to check bullet diameter.
John - Thanks for the compliment and the photos. I have that short .450. My guess is that it was a special-order for some kind of Howdah pistol, but that’s only a guess.
The .450 Macdonald was identified by Fleming in his book. Where he got his information, I don’t know. I haven’t caught up with him yet.
On the bottleneck rifle round, how long is the case? From the bullet measurement it is a .450, it could be a No. 1 musket.
Yes, “.450 Adams” = .450 CF. Also, here’s all I have on the .476 Enfield:
[i]The ammunition originally proposed for use with the Enfield revolver in 1879 was of the Boxer type, although by the time it was approved for service a solid-drawn case had been decided on. Three different configurations were proposed, as well as several in solid cases:
- RSAF 646, Short Bullet: 19.25mm case length, 19.43mm bullet length (Designation is the Enfield design number.)
- RSAF 646, Long Bullet: same case as above, but 26.54mm long. Both had a rim diameter of 12.9mm.
- RSAF 658: 12.7mm rim diameter, 21.8mm case length, 22.7mm bullet length.
All three, presumably, used the standard military style brass tube with blackened iron rim. No specimens available for confirmation.[/i]
Unfortunately I don’t have a footnote as to where that info came from. If I can find it I’ll get back to you. [/quote]
