After the shot, 3.5" Nitro Hevi-Shot hulls stick in the chamber of my 870 super magnum and in my Beretta Extrema. I have to take the barrels off and pry the hull from the chamber. The unfired rounds chamber fine. It appears the brass expands during the shot and causes the sticking. Anyone experience this and if so, do you have an explanation and/or a fix? Thanks.
Shooting an xtrema: that was part of the problem with nitros not to mention they were making my point of aim go way off. The expense (8 to 9 dollars a shell) wasnt worth it with all of the trouble i was having with the shell. My gunsmith was concerned that a shell could make the point of aim go off that much. He was thinking it must be an extremely hot shell to cause the multitude of problems. Just made sense to switch to a more economic shell such as Hevi 13. In my xtrema
Hevi 13 3.5/2.25/7's will shoot 300 pellets in a 10in circle at 40yds. I noticed with the 4/5/7 nitros most of the holes i was looking at in the paper were 7's. The 4's and 5's were few and far between. Not to mention the wax problems with the end of the shell. Wax coming off the shell and possibly wax in the reciever,barrel, choke etc. Now that turkey season is over i bought two boxes of hevi 13 7's for 13.50 each at a store in alabama last night. I will never pay 8 to 9 dollars a shell again.. :anim_25:

preacher - here is link to a thread where a member on this forum tested Nitro's and found them well above SAAMI
the 51013 loads do that out of one of my mossys..havent tried the other to see if it will shuck them out or not. it also does not want to eject te hevi 13 7s tho...so i dont know whats goin on with that gun..if i try to eject bout 2-3 times, it will kick it out then
Admittedly, I don't know that much about shotgun pressures, but with centerfire rifles if the cartridge is hard to extract, I would not shoot that load again.
Could it be some inferior cases?
Ok a few thing will make this happen. One is the head space is off. Look to see if it mushroom the rim of shell. Now not think that is it but could be. One more is that the chamber is open to big that let's the brass swell so ejector can't get a hold of it. The other thing is that it is a hot shell that builds a lot of chamber pressure. Then small choke on top of that just add to it. Now one thing we have found is that a Fiocchi hull will swell up and this is with just plain old bird shot.
If it was a head spacing or chamber tolerance issue it should show up with other ammo as well.

I think so also just put the things out that will make it happen. I think the shell is hot.
loaded to hot
always have been
My Benelli handles them fine so far
My Benelli handles them fine, my shoulder not so much.
I was having the same problem with the hevi 7s 3.5in out of my 835. Got a extractor and spring on the way so hopefully it will fix the problem.

It's a classic sign of way high chamber pressure.
And it's very common with Nitros.
Thanks for weighing in Hal. I suspected that, but did not have the shotgun experience to back it up.
We have joked in the target world about back yard builders. Not a thing wrong but that we are tuning on a bomb. I have some stuff that I find of things that go bad. I have saw actions busted barrels blown up and this is with just plain old loads. This goes back to the fed fcw. Folks shoot it in a small choke it can go bad. It is not what choke,gun,or shell we shoot it is all about us all being SAFE.
I will ask them if they test it and how and if they provide test results. They may be pushing the limits with their test guns which means there could be some guns that would be be over-pressured with the same load. Do major ammo manufacturers have a % of SAAMI max they won't exceed?

I've seen this in my BPS. Never in my 870.
Never had one stick but have heard about a couple. But also heard about that from other brands as well.
it has done it once in my 1187.

Hard to imagine a company that sells to the public that doesn't pressure test their product (maybe they do). It is one thing to load them for yourself, but selling over pressure shells to the public? Talk about some liability issues.
I have some 20ga shells that a co worker gave me,so far out of 4 shots no problems
I bought 10 3.5"12ga shells 2 or 3 years ago
4 had to be knocked out of my 835 with a steel rod
5 had the same thing happen in my brother's 870 SM
I threw the last one in the strong river
NEVER will buy that high priced junk again
My buddy had some stick in his gun and had to fire them to get them out. He's no novice but couldn't pull, rack or any other method get those out. Wasted three in the OK dirt. I've experienced it too, but not that bad.
Ouch!
