For the ammo, since the original 455 Webley loading was a 265gr, I figure a steady diet of Buffalo Bore 255gr 45ACP +P rounds will work the best.
They might work best if your intent is to use a factory round to wreck your Webley.
One of the drawbacks to our forum (and all written text) is that without something to stand out and identify it, sarcasm is difficult to determine.
Here we often use the smilies to show emotional intent.
is usually used to show intentional sarcasm. Or you can just write something like "sarcasm intentional", etc. If you don't, someone(s) is going to think you are serious, and that can have disagreeable, and even dangerous consequences.
If you are making a sarcastic, or tongue in cheek kind of statement, or even complete BS in order to be funny or to make a point, PLEASE use a statement or smilies to ensure people understand, and so they don't take it as being seriously meant.
I doubt that the '60s importers made any effort to warn buyers against shooting their modded revolvers with modern, smokeless loads?
Probably not..if they even knew... it was a different era, and there was neither a law, nor a generally held compunction to inform people that fire burned and water was wet. People were generally expected to know what they were doing, and if they didn't bother to do that, what ever happened was their fault.
Risks were assessed differently then. Early 60s cars had neither seatbelts nor safety glass. Heck, back then, a lot of Doctor's smoked!! And I don't mean they went outside and had a smoke I mean they smoked in offices, examining rooms, and anywhere else they felt like it, so long as wasn't near in use oxygen...
A much different attitude prevails today, and indeed is codified in various laws.
