TC breach ?

[good ole boy]

Thanks.I don,t currently need one,I was just curious to see what it looked like.Do they cross thread em or heat treat em cause I,m tryin to figure out why they would be so hard to unthread.Are they hard also to replace?

 

[Zonie]

No. TC does not intentionally cross thread the breech and then force the breech plug in place.

They did just tighten them up way more than was really needed.

As for the special removal tool that they sold, they quit selling that when they started getting barrels back with warranty claims to repair or replace the barrels that had been damaged by the owners who used the tool.

 

[good ole boy]

So your sayin they are just hard to break but thread out and back in fairly easy?

 

[Zonie]

Sure they thread out easily after you break them loose.
They also thread in easily until you hit that last little bit. Then it can be tough going for a while. :rotf:

The wrench was a rectangle piece of metal. Inside was shaped to fit the barrel flats, but on one side it was cut out to fit over the snail. You slipped it up on the breech, then used a very large wrench, to get a hold on this special made rectangle piece of metal. Then unscrew the breech plug. It would take a very large vice, with soft jaws, to hold the barrel, and prevent any damage. Plus the specialty piece, can damage the breech plug.

Do the Traditions and Lyman AND cva factory rifles have the same patent breech design as TC?

 

[Zonie]

No.

The Lyman is very similar to the TC but the guns imported by Traditions use a breech like the old CVA's.

The rifles CVA and Traditions both import(ed) have a breech that looks like this.

As I recall the threaded shank on the 15/16 acf breech plugs are 5/8 inch long , the same at the thread diameter.

I took mine apart abut 5 years ago. Once it busted loose it spun out fine. I could not put it back as made. I ended up taking some material off the back of the barrel to get it to index using normal torque values.

I do not remember if the front of the plug mated with the internal barrel shoulder properly. It probably did not. I don't remember tweaking it so that both shoulders mated at the same time.

Finally removed the breach, nocked this out of the barrel...



Someone broke off the end of a ramrod in it. Now out. Barrel is fine.time to go shooting.

Breach removal was a five minute job start to finish. Local gunsmith had breach tool and aluminum m barrel jig for his vice clamp. One smack on wrench with hammer and it unscrewed by hand.
