T/C Encore primer blowback???
 

I'm tired of the mess I get with blowback when shooting my Encore. I wonder about drilling the hole in the breech plug a little larger to solve my problem. It seems the hole in the breech plug in the newer T/C's like the Triumph is much larger. Good idea or bad? Thanks

Blowback? I got an Encore this past spring and have had it out a couple times. I am amazed at how clean the breachplug is where the primer sits. I also have a Knight Revolution and it gets filthy from the primer.

I wonder why yours would get so dirty if mine doesn't?

I would think a larger hole means more blowback coming thru that larger hole.

Well I would contact T/C and see what they say. But it makes no sense that there should be blow back out of that rifle. But then when has a muzzle loader needed to make sense.

You need to make sure you are using the primer extractor. Some people take those out. You should see a difference.

I am using the primer extractor. I have two breech plugs. One is the cupped style and the other is flat. I have blowback with both.

What load are you shooting? Do you get blowback regardless of light/heavy powder charges?

Myself, i have no experience with the Encore, so i have no first hand knowledge of issues of that rifle. What i have done to cure blow back in my rifles is reduce the head space 3 different ways.

The simplest is to use an o-ring. This involves using a drill to make the primer pocket some deeper, so the rifle will go into battery with the o-ring in place. One needs to 'sneak' up on the correct depth. Drill too deep, and there will be no seal, and the innards of the primer will walk out of the cup when fired.





The o-ring pretty much seals the area at the base of the primer, when it is compressed, and is good for 25 or so shots. This works.





Another thing i have done, was suggested by Screwbolts, when he pointed out that my breech plug had flame cutting in the primer seat. This involves drilling and tapping the breech plug to receive a 3/8 x 24 grade 8 bolt.





One can then make the primer pocket less deep so that when the rifle is put into battery, the primer is crushed ever so little. This creates a 'seal', and has reduced blow back to zero in one of my Omega.





In my Accura what i did was make a breech plug from a grade 8 bolt, and by making the head space some less than factory, was able to reduce blow back to near zero.






The CVA breech plug is on the left. The length of the home made breech plug with the primer in place is about 0.020" longer than than the length of the CVA breech plug with the primer in place. This results in a crush fit when the rifle is closed, and hence reduces blow back.

Sometimes all that is needed is a change in the brand of primers. My Encore stays clean as a pin with Winchester 209 shotgun primers.

The head space in the encore is adjustable by using stainless steel shims behind the firing pin block, it sounds like yours needs checked.
