ok guys it took some thought but here is my idea on how to get rid of the sucky vent liner. the only thing is you have to use a standard bolt action bolt. in other words a centerfire bolt. buy using the bolt as a part of containing the pressure we can forget the screw. my firing pin module will help contain the pressure and seal the flash hole by allowing a little movement in the breech plug bushing and using an o-ring or piece of rubber. then after you fire it you can knock out the large rifle primer with the firing pin. check it out and see what you guys think. sb [  |

I may be wrong but the ml-I had a locking bolt (locking with lugs into the receiver )that the feds tried to require a ffl to ship and sale that is one of the reasons savage changed to the Ml-II

The part that contains the primer is that the bolt or a removable item that contains a fireing pin that strikes the primer after the pin in the bolt strikes it?

yes to the first question and the answer second question is there is a firing pin in the module that the firing pin in the bolt strikes.

all of the t/c encore muzzleloaders have to be bought at a gun store-its never slowed down there selling them. but you are right that this set up will take a standard c/f action to work.

I might be missing the point here, but my question is what's wrong with the ventliner. I change it whenever I lose my accuracy and go on with my life.
I also believe that the venliner is important to the function of the MLII. If you look at the drawings for a standard rifle cartridge you will see the primer sits on a shoulder (anvil) and the fire from the primer is concentrated into the powder from it.

I thought the same thing when I first read this thread (What's the big deal with the ventliner?). Of course, when I cleaned my gun today, the vent wouldn't come out, and the stupid thing stripped on me. Now I've got to get someone to drill the d**n thing out.

If you want to get rid of the Vent liner then RB and Pete put in bushings (I'm a big fan) I have 4 breach plugs 2 with vent liners (sitting in range box just in case) and 2 RB plugs in my guns and they shoot 1in at 100yrds(sons gun) and 1 1/4 (my gun)

well for you guys that shoot 200 or less shots a year probably nothing wrong with the vent liner. but for those of us shooting at 2,000, 5,000 or more shots in a year it gets old changing them. with the system i am showing the module holds back part of the pressure of firing. since thwe large rifle primer is at the powder charge you dont need a vent liner and there is no where for the pressure to go but out the end of the barrel which means accuracy should be increased, which is what i thought we were after???

Two points.
What happens when the sliding bushing sticks? Or how do you propose to maintain it?
Do you think an o-ring is up to the task of sealing a couple thousand hot pounds per square inch?
Guess I'll add a third. Using a pin to hit a pin to hit a primer may increase the lock time of your rifle just a bit too long for good accuracy.

not really, on the lock time on a sharps isnt bad and its a two piece firing pin and the one the hammer hits is at a hard angle. as far as pressure i would have to really sit down and look at the square inches but it wouldnt be much. how much brass is between you and over 65,000 psi in some cartridge guns is there??? not much. the module would be solid brass with only the firing pin hole in it. the bushing would be press fit and will only have to move a half a thousandths. havent you ever chambered a neck sized cartridge into a center fire??? the bolt has a lot of camming power. it will push the bushing back just a little because its being pressed evenly from the center. then upon firing it will push back and the process starts all over again.

Not trying to be negative but if the bushing moves would there not be a wear/ fit problem occuring in a short period of time with that friction from movement?

hey ed thats ok, it is only going to move the thickness of the rubber o-ring or piece of rubber.
its hard to see in the pic but the nose of the module is a close fit into the breech plug.
