Sometimes the tube was not threaded in right as it may have been loose and the shot coming thru will feel a slight obstruction and something will give plus a snake bore passing thu will only cover the ridge if the chocke is loose and put the deposits in the loose threads. Most likely you didn't take the tube out cleaned oiled the threads and tighten properly.

this is all weird to me. was hunting with a guy that was shooting a benelli with a Carlson on his 4th hunt and he was shooting 3 1/2 BB Kent's and his barrel looked identical to that. Happened about mid morning and his gun was in a duck commander gun boot.... Carlson said his fault kent said his fault. benelli took the blame for threads and gave him a new barrel and choke? don't ask me why.. weird coincidence. IMO Kent's suck.

I am assuming no blockage and trying to approach this from that angle.
If true...the choke tube is suspect.

If you want to understand what happened...look up these terms. The "engineering" terms for what happened.

1.Engineering Fatigue
2.Engineering Stress
3.Stress Concentration factor

I suspect there was a tiny scratch from the machining process (stress concentration factor)
The part stressed, fatigued, and then cracked off.

I went to engineering school and spent a LOT of money to learn this crap. Nice to actually apply it sometimes.

I still wouldn't use that barrel until Benelli says it's OK. :thumbsup:

If that was the case, IME, and by looking where it is broken off, A stress factor where the knurled end meets the barrel (where this one separated) would not have caused the barrel to bulge or Flare like it did being that that event would happen outside the actual barrel. I am very curious as to what the mfr's say about it as much as the rest of you are. Just want to add it to my knowledge base :biggrin: .

Did you send it to Carlsons or to Benelli?

I know its a little off topic,

But I shoot the same choke, and as I'm reading this thread, it made me think that I normally only tighten the choke as tight as I can get it with my hand. I rarely use the wrench, since I can twist the extended portion.

Is this bad practice? I don't wanna be another dingbat with a gun.

Hand tight is usually good enough. Here's the dingbat with the gun problem.. :lol3:
Most problems arise from people not checking their chokes often while hunting, especially shooting steel shot I check my choke tube at least every five rounds. Even shooting lead shot they get loose, you have to be consistant in monitoring any tube you have in your gun. This I have seen over the years is how mot tubes get ruined, most people don't check them, they get loose and they keep firing rounds through them and destroy the tube. I takes about 20 seconds to check and tighten a tube....worth it in my book.

I do check mine about once a day but I can not remember having one come loose. I use anti seize on them and tighten them with the supplied tool and they do not come loose. Even shooting 200 rounds of sporting clays in one outing I have never had to tighten a tube after it was installed. I assume it can happen but I have not personally experienced it. I have to remove them with the tool also but have never had one of my personal guns enjoy the experience of a stuck tube. :beer:

Purchased a Trulock choke with B on the packet. A shop assistant attempted to sell me a Beretta optima choke for an M2, which is the same. My arse!
