Guys.
A long time back I had a few customers ask if I could install my plug in the Encore/Apex barrels. I said I could so a customer (Jay) and (Phil) sent me their barrels. Upon receiving the barrels and inspecting them I quickly realized my current plug design was not the best choice for the conversion. On Jay's factory Encore barrel I decided my plug was just a little to big. If I had installed the 5/8-18 plug in his barrel the plug would have been getting awful close to the scope mount screws and that was something I wanted to stay away from. So I took some measurements and designed what I will call the perfect plug for using in the brake action guns. I has a 9/16-24 fine thread with a rear sealing shoulder and uses my current 45-70 modules. I installed this plug into 9 rifles last week and test fired them for ignition, All Rifles performed perfectly.
Next I inspected Phil's rifle. Phil's rifle features a Bullberry Barrel and he wanted to switch from the leaky 209 primer system that was currently installed in his gun and go with the LRMP I use on my bolt action Muzzleloaders. Well, upon inspection of Phil's rifle I found a plug that has 11/16-20 threads so in order to keep his barrel and convert to my system I had to design a complete new plug for this to be possible. What I came up with was a plug and primer module combination that is .100 longer than the original system. This allows the installer to re-machine the shoulder and set the headspace.
All of my plugs now feature a tungsten bushing and set screw. I decided it was easier for me to machine all the plugs to except the bushing and to never have to worry about wearing out a vent hole again. Even though I have a few old style plugs out there that have a reported shot count up in the hundreds and still going, It's one less variable to worry about.
The picture below is of the new plugs. The plug on the left is the 9/16-24 and the one on the right is the 11/16-20. The picture shows a primer module, plug, bushing, and set screw..
I had some help from a good friend that drove up for the weekend to hang out and give me a hand testing all these brake actions and we decided to make a video of the testing and I just got it up-loaded to youtube so I hope this video answers any of your questions and is a little entertaining as well. Sit back, grab a soda and enjoy the video..
