Thank you sir. Strange, that one was SSK and this one is a factory CVA.

 

[jsteurrys]

I would contact CVA to see what their response is to this issue.

I t looks like it might have been overtightened? The CVA is thinner there, than the SSK plug. But i didnt think it could be overtightened that much.

 

[biggamehunter78]

I doubt that’s possible with the massive shoulder on the back side. It was in there finger tight.

CVA said overpressure… “they only recommend 2F powder” not 3F. Easy cop out IMO.

Someone had a SSK Breechplug do the same thing.

I thought that one had been dropped and dented?
Guess i missed that one.

There is a procedure to follow using a new plug. Did you follow it? Look in manuel.

No that would not make it look like that. Looks like bad machining of the threads…

It looks like the threads have some grease on them to me! The end of the plug is mushroomed!

I think it was a bad plug from the get-go. Order another.

 

[biggamehunter78]

It was fine before I shot it last. Not belled at all and went in and out easily by hand like they’re supposed to.

I suppose it could have been thin in that area from the factory MrTom. Didn’t think about that, but it didn’t look markedly different from the others I’ve had in the past.

 

[MrTom]

The shoulder on the finger nut would stop the plug from going in so far as to cause belling like that. I think the plug wasn't finished at the barrel end to the proper length. Send that one back and request a new one.

You don't mention what load you'd been shooting either. Knowing the powder, the charge size and bullet weight can also help here. A mega charge with a medium weight bullet might cause this too. What are the load details?

 

[txhunter58]

Yep, powder/bullet combo info would help. Did you notice it kicking extremely hard on any shot? Double loading with powder can and does happen.

 

[biggamehunter78]

100 gr T7 3F pushing Hornady FTX 290. It’s a healthy load but far from “magnum”.
