.455 Webley Conversion, Headspacing Rings:
$18.00


These loading discs are machined from 4130 steel sheet. They havebeen produced with milling machine and lathe to allow convertedWebley No. 1 Mk V and Mk VI ( I can alter for earlier Mks ) revolversto shoot the original 455 Webley, Colt, and Eley caliber ammunition. Using original .455 Webley ammo is safer in these revolvers than some45acp ammo. The original factory ammo is loaded to the correctpressure and uses the correct bullet to give better shooting results. A customer has reported better accuracy with no keyholing and groupscloser to point of aim using .455 factory made ammo.


These rings are made .047 to .049 inch thick to “replace” theamount of material removed from your cylinders in converting to .45acp use. I can supply the rings in different thicknesses toaccommodate your revolver, however, if it has unusual head-space. This can be measured by using automotive feeler gauges stacked in acombination that will just enter smoothly the area between rear ofcylinder and recoil shield at the upper position. This dimension isusually .095” to .100”. Most buyers have not measured this; Ihave sent the average thickness and that has worked well for them.


They are meant to allow the use of the original thinner rimmedWebley ammo in guns that have had their cylinders and extractorsfaced off in a lathe to make them accept 45 Auto Rim and 45 acp ammowith clips. Your converted Webleys can with these rings use original.455 MkI and .455 Mk II ammunition. 455 ammunition does not snap intothe rings. They are only positioned with corrected head-space toallow sure ignition and safe firing. Positioning has been assured byusing a rotary table on the milling machine and following thepractice of drilling, boring, then reaming the cartridge holes. Theseare offered in-the-white. The steel will readily accept cold bluing,rust bluing, or hot water bluing.


Several buyers have wanted rings to enable the use of .45 Coltcases that have been shortened. Let me know if you want this and I'llsend a ring of appropriate thickness for use with .45 Colt or .45 S&WSchofield cases that have been shortened. The most accurate way forme to supply these is for you to give me your revolver's head-space,but again, average thickness for this type case will likely workfine.


If you are purchasing a ring to use in a Mk I, II, III, or IVWebley, tell me and I will reduce the outside diameter to 1.718”to match the O.D. of your cylinder. Rings are now 1.745” O.D. ForMk V and Mk VI. A recent buyer informed me these also work with aWebley WG.


In the conversion process of machining off the rear of thecylinder and the extractor, a few of these guns have been left with astep at the base of the ratchet. If your gun has an extractor with astep or larger diameter section at the ratchet's base, please informme when purchasing and I'll send a conversion ring with larger centerhole to clear this. So far, only about 2% of my customers have foundthis on their guns. No extra charge for modifying the ring to fityour gun.

An extreme case of needed modification is shown in the lastpicture. Out of more than two hundred parts sold, only two customershave needed a ring like this to accommodate non-flatness on the rearsurface of their revolver's cylinder and extractor. Only the tips of the extractor engage the conversion ring made like this one. An additional $5.00 chargeis needed to make a ring such as this.


Smith & Wesson revolvers chambered for .455 originally andconverted to 45acp have different dimensions. I do have a few of therings made for S&W .455 Mk II, the second model. Write if you areinterested in a S&W ring before purchasing from this listing.


The ammo and the revolver in the pictures are NOT for sale. Theammunition you will see is marked 45 Colt but the case rims werethinned to approximate Webley ammo dimensions (.033 to .039 inches)and shortened to be used as .455 cal..
