The mold is a brass 4 cavity with Cramer retained pin system. Very slick. Blows the Lyman and RCBS moulds away.

I've heard only the highest praise (such as here) for MP's products. I'm half tempted to get one of those moulds for my .455 now that I'm going to start "rolling my own" for my Martini .310 Cadet.

Have you seen the 200 grainers for the .45 ACP/AR with the hexagonal HP?

I have a 454" 250 gr mold similar to that one with penta-pins(5 sided) hollow points. I have 4 MP molds at home and some more on order through group buys on Cast Boolits. They are excellent.

Image of the one I was thinking to use. It's for a .450 adams. .001 of an inch difference in diameter. .454 vs .455 for this one.

My RCBS 265 gr HB mould dropped slightly undersize from what it was advertised to be. The hollow base makes up for it.

The hollow base expands to fit and seal the bore. That may or may not be necessary depending on your revolver.

A lot of the Webley MKI and MKII .455 revolvers are throated at .452" and some have slightly larger barrel ID of .453" or 454". It doesn't really matter if you start out with a .454 or .455 bullet in that case because it gets squeezed down to .452 before it gets into the rifling. In those revolvers the hollow base works better because the skirt of the bullet expands to fit.

I have shot .455 and .454 flat based bullets in several webley revolvers with good results, but other revolvers shot much better with the HB bullets. The HB bullets shoot well in all of them, the FB bullets are a bit more hit and miss. It depends on the actual dimensions of the throat and barrel in each individual revolver.

I'm thinking then that this is a good venture. So in aspect to the mould I posted for the .450 Adams, at .455 diameter, casting lead to a soft enough mix, do you think I'd have any problems even if the bore was .452-.453?

As you mentioned, it should squeeze down to fit, so the .455 would be negligible. Best case is it is .454 and little squeezing is needed.

The hollow base is how I will go for sure then.

You can buy a .452" Lee sizing kit for about $15. The kit comes with Liquid Alox for tumble lubing as well. You should lube those bullets before you shoot them.

But I wouldn't worry about resizing personally. 2-3 thousandths isn't a big deal with soft cast bullets at these pressures and velocities. I shoot a lot of soft cast .455" cast bullets in a .452" and .453" throated revolvers. You wouldn't want to do that with jacketed ammo but soft cast bullets are very forgiving. In fact most people recommend shooting .001 to .002" oversize cast bullets for best accuracy.

I bought the last 452 HBWC mold from MP-Molds, it drops the bullets as 0.4525 using wheel weights. When I slug my MKIII Webley the throat measures at 0.450... so I should be able to lube these and shoot as cast without any sizing?
 
I have been using a RCBS 455 mold for mine. I castes about 100 boolits so far but I have not shot any yet, I have been to darn busy!
 
I loaded .38 Special 148gr HBWC'ers upside down over 3-3.5gr of Unique.At 100 yards on a steel barrel they would penetrate one side expanding to .75 caliber and leaving a welt on the other side.Harold..........no reason one couldn't do the same with a lead .45 slug

My mould was a .454". I size down to .453" and shoot them in a variety of webley service revolvers sthroated from .450" to .453". Any softcast HB from .452" to .455" will be fine if you're using a soft cast bullet.

I shoot bullets that are .003" over size in my webleys all the time but I use a mix of 1/2 lead and 1/2 ww to get softer bullets. Pure ww is harder than I like to use in these pistols for 2 reasons:

- softer lead base will expand to grip the rifling and seal the bore = less leading and better accuracy
- softer bullets create less pressure, especially in a tight throated firearm like the webley service revolver.
