Alfa .357 Muzzle Loading Revolver

6" barrel, 4" barrel, 3" barrel and 2" barrel.


The Alfa is a section 1 firearm and can be held on a firearms certificate. To purchase one you will need a variation for a cal. .357" muzzel loading revolver and one variation for each extra cylinder you want.




So that I can manufacture Muzzle Loading Revolvers, Alfa supply me with part built .357 revolvers, that have never been completed and have no cylinders, thus they are not Section 5 prohibited firearms. I then carry out various modifications and fit a muzzle loading cylinder of my own design, the completed revolver is then proofed as a Muzzle Loading Revolver.

Bushnell RXS-100 red dot sight. The RXS-100 has a 4 MOA dot size,

8 brightness settings and windage/elevation adjustment of 1MOA per click.

Britarms .357" Muzzle Loading Revolver

This project hasd been on jhold due to the case with Border Force causing lack of funds to finance developement.


We are currently making test components and the tooling to make them during production. The pictures show the test frame being machined.


8th November 2017


These pictures show the progress so far. Aluminium frame and barrel shroud prove the machining fits and tolerances.    Most small parts are made and working correctly. It has fired primers and the trigger shows great potential.                      The adjustable front sight gives 3 pre-set elevation settings. The rearsight will be adjustable for elevation and windage.


March 18th 2020

I now have a functioning prototype and am in the process of getting all the production parts in place so I can make a second revolver using production parts. Once that is done and I am satisfied with its performance, then I will be making the first small production batch and I will know how much I need to charge for them.


June 2021


As I have decided to re-design some of the internal components we are sort of back to stage one, until I get them in production format and can test their function. Frustrating but necessary I'm afraid.


                                                                                                  April 2022

I'm still waiting for the final production parts. so that I can check out the final design.


                                                                                                 February 2023

Due to the seizure of the Alfas and the lack of funds due to no sales, the Britarms ML Revolver is on hold until I can afford to spend more money on it.




Using the Alfa Muzzle Loading Revolver

To load the revolver the cylinder is removed by sliding it rearwards off of the open yoke, spent primers can then be ejected by using the pricker provided through the flash hole.


A measured charge of Powder is poured into the chamber and a bullet inserted into the chamber. The press provided is then used to press the bullet in, seating it just below the chamber mouth.


When all six chambers have been loaded the cylinder can be fitted back on to the yoke, and the primers may then be fitted into the primer pockets, seating them firmly home with finger pressure. Once this is done and the yoke has been closed the pistol is ready to fire.

Use more than the Maximum listed above or with other powders I will accept no responsibility for damage caused by overpressure.


Generally you will get the smallest groups using soft lead hollow base wadcutter bullets. However I suggest that you use solid base bullets until you are familiar with the gun, to eliminate the chances of leaving a hollow base in the barrel, because you inadvertently used too powerful a charge.

You will find that as you decrease the charge one tenth of a grain at a time, the group size will decrease, until you start to get the occasional flyer because they don’t all stabilise properly; Come up a couple of tenths and this is your "standard" charge. When you change something, you will need to check again.


I use .38 fired cases with the necks "belled" to hold the measured charges, using a wadcutter inserted in the neck as a stopper. On the range you pull out the bullet, pour the charge into the cylinder and press the bullet in on top.


Your local gun dealer should be able to get wadcutters for you. Edgar Brothers will supply them with Sellier & Belliot wadcutters. I can supply bullets made to my specifications but carriage is very expensive, so you would need to pick them up from Salisbury or buy ten boxes at a time and get free carriage.

The Revolver is designed to use a 148 grain soft lead Bullet of .357” Diameter, propelled by large grain slow burning powder such as Green Dot, Unique, Herco or Blue Dot. Ignited by a 209 Shotgun primer. (Do not use Magnum primers). These large grain powders will not leak from the flash hole during loading, and, with the large flash from the shotgun primers, will give a more progressive burn than obtained with fine grain powders, where all the powder can ignite before the bullet starts to move. This causes a spike in pressure which can fracture primers where the firing pin dents it, causing gas leakage and a build up of copper deposits on the firing pin. The build up of these deposits can cause the firing pin to fail to retract. This will jam the cylinders rotation.


The Revolver has been proofed to .38 S&W Spl. pressures, so use the powder manufacturer’s data for .38 Spl with a 148 gr lead bullet when selecting a charge weight to use. Do not exceed the service load laid down, as excessive pressure causes an increase of burn rate which can cause severe overpressure and damage to the revolver.

If using Hollow base wadcutter bullets use a small charge to reduce the pressure, or the base of the bullet may separate from the head and possibly cause a bulged barrel when the next shot is fired.


When you buy the Alfa it will come with the loading guide above and also with a coaching guide on how to use the firearm safely and accurately.

Browning Buckmark .22 Long Pistol

Due to Browning no longer manufacturing the Buckmark .22 rifles, we can no longer get new rifles for the conversion to long pistols. However if you can find a used rifle I will convert it for you. Contact me for more details.


However, as I have decided that the Ruger 10/22 is a non starter for a LB pistol,

I am working on making some Browning Buckmark frames and barrels to produce the "Britmark .22 Long Pistol".
