Following on from my post re "Stevens Ammo Dimensions" I decided that I would like to make my own special ammo because Stevens 25 rimfire is all but not available here so I have made a new breach block for my old Stevens Favorite to covert the gun to centre fire so what I needed was reloadable center fire ammo made to 25 rimfire dimensions. With today being raining it was a perfect day to go into the shed.
I tried to match up the size advised in my previous post but things did not quite stack up so I had a cunning plan to determine the exact size of the chamber of my old gun I measured it as best I could (I could not go that deep into the chamber with the nibs of my vernier) then turned up a soft hollow copper plug of around the correct size. I then carefully forced this into the chamber where it easily formed to the shape/size. I then used some thick metal polish on the copper plug to lap the chamber and get a good clean fit.
From there I could easily measure the plug and have made my first prototype brass case complete with centre fire primer pocket. So now I have a reloadable centre fire case to 25 rimfire dimensions.
I have tried it out with a light load of blackpowder and a wad and IT WORKS !!! great fun.
The next stage is to make a few more cases then a mould (I may go for .25 balls) then try it out for real.
I know it will be far from accurate but it is a great fun project and should make a good little gun for the garden, just bit more fun that the 22.
See photo of the plug the first case and a 22 for scale
