Do you have any loads yet for your 450 that you could share? My antique will load and shoot .455 but it is a 450 revolver and would like to come up with some dedicated 450 loads for it rather than relying on factory or reloaded .455.

Here is a old 1979 Handloader Magazine 4 page article on reloading the .450 revolver cartridge starting on page 6 -

Just posted this on another thread, but I really liked 3.2 grains of Trail Boss or 700x powder pushing a 265 grain hollow-base projectile. very comfortable load.

3.2 grains of TB behind a 265 grain projectile? Wow, I'd be worried about squib loads! You must be able to count to 3 before the bullet hits the target!
I go as high as 3.7 grains of TB behind a 100 grain projectile in my Swiss 1882, though it's a little hot for my liking.

webleys are a much weaker design then the swiss 1892

It feels pretty good from the Webley. that is about as much Trail Boss as I can fit in the casing without compressing the powder when seating the bullet. But for sure the load won't set any speed records.

Webley ammo and large bore guns in general terms are much different species . Swiss is a small bullet going fast. 455 is big going slow.
Just for the record. I want to reload for S&W not webley so it can go bit hotter. That gun in many instances was bored out with 45 colt. One my friend owns is original 455 used by British and Canadians in WW I
