Bowhunter82 Posted January 2, 2011 Share Posted January 2, 2011 (edited) I have an SBE II, that I've had for about 6 months, and have only shot about 4-5 boxes of 3.5 steel 2's and BB's out of this year. I have only shot modified choke. While doing maintenance on the gun yesterday, I took the choke tube out, and noticed a stress crack down the entire choke. Has anybody had this happen / is it at all common to these crio tubes? Would it just be that the choke was faulty to begin with / metal was weak? I'm hopin Benelli will help me out on this one.

Guest cleefurd Posted January 2, 2011 Share Posted January 2, 2011 Unfortunately steel shot can and does cause this more often than lead. If the choke states steel is OK (MOD ought to be "FULL" for steel so my recollection is you're GTG), I'd check with the manufacturer, and indicate you suspect possible tempering errors subsequent to the heat treating process. Assuming they take your account at face value (which they should if they can examine the part for heat treating flaws), then you ought to get a replacement. Good luck with it, and hopefully it did not bulge the barrel adjacent to the threads when it split. Quote Link to comment Share on other sites More sharing options...
Bowhunter82 Posted January 2, 2011 Author Share Posted January 2, 2011 The barrel is okay to the naked eye, and I can screw the IC choke in fine. It tightens up and seems to be alright. A further question is, would I possibly need to send the barrel in for inspection of some sort in case of small stress cracks/failures in the barrel now, that I just can't see? I don't need that blowing up on me. And, yes, the modified is "steel shot ok", anything tighter and I would have a problem. Quote Link to comment Share on other sites More sharing options...
GTPSC Posted January 2, 2011 Share Posted January 2, 2011 In my opinion, I wish steel shot loads would go the way of the Dodo! I say this because steel shot is "hard" stuff compared to lead and the alloys. Steel shot is hard on barrels as well as chokes because there is little to no compression of the pellets as the shot travels through the barrel and choke. Imagine the pressure on the threads in the barrel and choke as the shot exits! The new alloy loads are easier on the metals and generally give better performance then steel. Steel loads, however are usually cheaper. When I got into the business of making my own design choke, I decided to go with 17-4PH SS. It is a bit more in price compared to steel and harder to machine and hard on tools, but the tensile strength is very high! That means it can take steel loads and survive by giving just a bit! A lot of the aftermarket chokes use 17-4PH SS. GTPSC http://www.blackborechokes.com Quote Link to comment Share on other sites More sharing options...
hattles Posted January 2, 2011 Share Posted January 2, 2011 ...I would suggest contacting Benelli customer service about sending the choke in for replacement. Quote Link to comment Share on other sites More sharing options...
Bowhunter82 Posted January 3, 2011 Author Share Posted January 3, 2011 That's what I'm gonna do, hopefully they will help me out. I just wondered if anybody else had heard of this happening. Thanks for the responses so far. Quote Link to comment Share on other sites More sharing options...
Bowhunter82 Posted January 3, 2011 Author Share Posted January 3, 2011 Talked to customer service today. They didn't seem too surprised at the problem. Sending me a new choke, and don't even want to see the cracked tube. Quote Link to comment Share on other sites More sharing options...

BEAR_ICE Posted January 3, 2011 Share Posted January 3, 2011 Talked to customer service today. They didn't seem too surprised at the problem. Sending me a new choke, and don't even want to see the cracked tube. Bowhunter82, Congrats on the new replacement. If you would, let us know how long it takes to receive it. So far it sounds as though their Customer Service is Awesome! I’ve never dealt with them but have heard horror stories. It’s nice to hear positive feedback once in awhile.

Bowhunter82 Posted January 4, 2011 Author Share Posted January 4, 2011 Will do..... Quote Link to comment Share on other sites More sharing options...
Bowhunter82 Posted February 13, 2011 Author Share Posted February 13, 2011 So..... It's been over a month, and no tube yet. I got a hold of Benelli again, and they said that it is on backorder, and they have absolutely no idea when I'll get it. Would have been nice for them to let me know that a month ago.
