Why couldn't you try the o ring in the omega or encore see if it works can't hurt only problem I see is the breech might not close.

With the Accura (or similar), if I had such a problem, backing out the firing pin retainer would probably be the better way to go so long as it didn't interfere with action operation and the retainer threads still had sufficient engagment. It would be easy enough to make a shim to go in behind the retainer but it might not be easy to achieve the right thickness. Bellm sells such shims for the Encore system and those might be fitted easily. If a .001" or maybe .002" wouldn't do the trick, I wouldn't mess with that either.

I want my breech plugs always snugged up but I will admit to having experimented with them just as Semi describes. In a rifle where a shim would work safely, that's the route I would take.

Have not considered this before or tried it, but how about an "O" ring at the base of the breech plug. I imagine manufactures played around with somthing like that and rejected it though.

Aha, I beat you to the punch on one idea finally! ;) Had the idea and mentioned it to Busta. He went to town with it and did a lot of testing with various O-rings. It works perfectly if you can find the right thickness o-ring and the life of the o-ring isn't much of a factor at about 3 cents each.

I still haven't tried it - there's been no need of it lately. ;)

The de Bange obturator is used on the breech face of artillery pieces that use bag charges. It positively seals the breech from powder gases. i would like to see a machinist make a minature de Bange obturator for muzzleloader breechplugs.

my ENCORE has some blow-back and it is not the breech plug ,it seems to come from the loose play between the primer and breech plug .

Man, that's a new one on me Falcon (sounds dirty, so I like it). Thanks for the link - it was an interesting read. If someone tried to market one for muzzle loaders using the original design they would probably get into deep government doo-doo with the asbestos.

Get this one.....I received a call from CVA today, they needed my credit card info for a scope mount and rings I returned that should have never been sent as when I ordered them I told the guy at CVA that I already had the Z2 Alloy Mounts and I wanted the older style CVA Scope Rings and Mounts, they were also See-Thru but the older style sat lower and were a better fit for my ACCURA and I did'nt have to pick my head up so far to see through the scope, anyway they sent me the same set! I called and they said they discontinued the other kind, dont you think they should have told me that when I ordered them. So I had to call CVA to return them and if you ever tried to call CVA you get put on hold for about 20 minutes, and they dont even have a 1-800 number, so when I got my phone bill today there were about $20 worth of charges for calling CVA to order parts!!!
NOW for the good one and back on the topic........I mentioned to the guy at CVA and Im not gonna mention names, about My ACCURA and the looser than normal hole on the CVA's Breechplug for the primers, and that they fall out if you turn the ML down. He said dont turn it down,,,,LOL.....it get's better......he told me to get a-lot of Carbon build up in the Breechplug and they will fit tight and not fall out! I hung up the phone........I did'nt need to pay for more bad advice!

i think what he was trying to tell you was.... Keep shooting! LOL. All of the inlines ive had. even my omega, the primers would just fall out if you tipped the rifle up. Keep shooting that sweet little shooting Accura and enjoy it. Im no worried about the dirty primers in mine.

If anyone has that type problem on the Encore { mine does not} then remember you cn adjust the head space to take care of it and if you use center fire barrels it is a good idea to check and adjust the headspace, if you reload it will make your brass last longer. Lee
