I'm trying to find my best option for reloading .45ac cartridges for my webley mark 2. I'd like the original bullet size of .454 in the acp case. Does anyone do this here? If so I'd love some pointers so I can avoid some of the trial and error process. Thanks gun nutz!
 
Just to clarify: which caliber are your gun and cylinder chambered for? Did you slug yout barrel and cylinder?

Indexing is often aproximate on revolvers of that period and I would use RN or flat RN designs. My LEE molds drop range lead at about .4535 and can be beagled.
 
Only issue I can forsee, is the expander not opening the case mouth sufficiently for soft cast bullets of that diameter. The case may end up sizing the base of the bullet when seating. Might be fine, and if not, a custom made expander would solve the problem. Maybe not a problem with hard cast bullets.

Cheers,
Stomp
 
I use a Lyman mould meant for 45 Colt. Pre WW2 bullet size of 0.454. Works excellent in my 455 Webley. I am using cut down 45 Colt cases with the rims thinned. As mentioned already your expander my be too small. I usually make up slightly larger expanders on my lathe which stops the case from down sizing the bullets.
 
In the past I've owned and shot .455 in Webley Mk. III and Mk. IV revolvers, also a Colt New Service and a S&W Hand Ejector.
I used a Lyman 454190 RNFP mold mostly (which is still listed as in production), and also an old Lyman 454424 (no longer produced) and sized my bullets to .454".
I used both Webley Mk. I and Mk. II length brass, including old 'balloon head' Dominion .455, newer .45 Long Colt brass modified to Mk. I specs, and newer Starline Mk. II type .455 brass.
The above bullets shot well out of all my revolvers, but the 454190 was my favorite.
I never had a cylinder modified for 45ACP, and my understanding is that moon clips are required to be used with that modification but are fairly readily available. If your .454 bullets in 45ACP brass aren't too big in diameter, and will load easily into that cylinder, then all's good.
As you have both cylinders you might want to see if shortened .45 Long Colt brass will fit the ACP cylinder and still leave sufficient clearance to rotate easily with no drag without needing rim thinning.
You also have that unshaved cylinder, and .455 Mk. II brass is usually quite available, so you can have the best of both worlds, but the 454190 mold would be the one for me.
 
Copies of the original 265 gr. Rn hollow base and 220 gr “man stopper” bullets are available from cast bullet makers in Canada. If you want to cast your own, Miha moulds in Slovakia makes moulds for these bullets.
 
.454" works great in the mk1 and Mk2 Webley revolvers.

You can get the traditional "webley" HB bullet mold from MP Molds.

My favorite bullet in the webley is from Accurate Molds. It's a 250gr Keith style SWC. It's originally my bullet design but anyone can buy the mold from their catalog.
