.486 i have a few antique revolvers and the cylider bullet end are all within a thou or 2 of the bore diameter. also most of these have a
genorous big forceing cone into the barrel.

Webleys have the forcing cone in the cylinder.
So you could have smaller bore cylinder "at the front" than the barrel throat. WGs are not something to compare to as many were bored for 476 i.e. straight through removing the forcing cone but even so they mic .450 - .455 (can confirm with my own measurements)
The way I read it is that this gun has the cylinder bore _wider_ than the bore.
Plus that massive cylinder gap suggests that something has been messed with.
Could very well have been bored to a short 410. I've seen some antiques bored for a cut down 410 shell for people to use to dispatch pests and hunt small game - that's according to the estate heirs... The guns I saw this on were not Webleys but Belgian guns originally in 455. Anyhow, if that's the case 45lc should chamber but may not be safe to shoot.
Check timing carefully. If you don't think you can or don't know - ask a gunsmith. If the gun is mistimed it is both dangerous for the shooter AND will get damaged quickly if used.

You may want to double check this. 476 and 455 use the same diameter bullet. 450 was negligeably smaller. Case length is what's different.
So 450 will work in 455 which will work in 476 but not the other way around - won't chamber fully because 476 cartridge is longer. If the cylinder length allowed many were re-reamed.

this speculation thing about variations does not apply here. this cylider forcing cone has been reamed , period. u can see some spots like
small shinydips where the reamer has not touched and a couple of chambers where the forceing cone would have started, real rough
cuting of the reamer. i have contacted CSC if they will take it back or at least exchange it. will keep u posted. thanks

I was responding to snurge's statement thst 476 uses a larger diameter bullet which I understand is not true.
So are you now saying that you did buy it from CSC? Weird thread... Anyhow, good luck!

It's a Webley thing - forcing cone is in the cylinder rather than the barrel. I don't know if they used a separate reamer or just a single one when reaming the cylinder chambers.
OK, there is a shoulder in the chamber, then a transitional area toward the mouth of the chamber. I've not heard the term forcing cone referred to before in connection with a chamber. It is my understanding that Webley chamber mouths can be smaller than groove diameter, and the hollow base in the bullet is expected to expand the bullet to take the rifling.
