.455 Load Data Required

RS2000CUSTOM · Nov 7, 2023

As per title

Am looking at loading some WW1 MKII .455 British
Sometimes known as Webley / Eley / British

I am looking at using a lead cast 265 gr bullet with Bullseye Powder

I have been advised to start at 3 grn's of powder and expect 750 - 800 fps

Has anyone any experience of this particular load or what do any of you use for .455 ?

Ammunition is to be used in a soon to be owned WW1 Smith and Wesson Triple Lock (See Pic below)

Any help greatly appreciated

Based on the load data I have that should be a nice light load.

Typing .455 Webley load data into your search engine gets you lots of source options.

A lot of the load data available is for full power loads and may be a bit more bang than I need.

I use starline brass and a Colt 45 255 SWC over 5 grains of unique in my Colt 1914 New Service. 750 fps

Wiki has the original velocity at 650 f/s. The Brits were really big on "dwell", or the time the bullet spent in the body. The Fiocchi Heritage version claims 850 f/s, which would seem to be +P, but then there's been a lot of changes in powders since cordite was invented, so presumably pressures are similar.

The Dec/Jan Handloader magazine shows the following for the load you are interested in trying in the MKII case:

265gr Hayley Alliant Bullseye 3.0 562fps

I load 4.5gr unique with a 272gr cast hp. Sized .457”. The load is geared to print sights at 50’. Lucky I had no windage issues. Bullets cast in modified
Lyman 322gr Gould Express HP.

That sounds exactly the load I am after and matches what I had been told by a member of our club - thanks

Also, remember that if you have a cut 0.455 Webley, DO NOT use regular 0.45 ACP rounds and clips as the 850 - 900 FPS (a "normal;" 0.45) is very close to a 0.455 proof load in the Webley MkV/VI. Dave_n

Star-Line is a very fine company and they have done a lot for us reloaders but they really screwed up on their .455 brass 1/10th longer and it would have been a mkI that could have been trimmed to the shorter length. All Webley, Colt and S&W revolvers were chambered generously to the longer length and then some. As a result of this handloaders have to load a much milder load for these old Warhorses.

Found additional load data in a 2014 American Handgunner. With the 200 gr Lyman 358430 bullet, 2.0 gr Titegroup. With the 264 gr. Redding/Saeco #955, 3.0 gr of Bullseye.

3.0 gr of Bullseye looks like the way to go with a 264gr bullet

Thanks
