benelli Super Nova: Shooting 3.5" black cloud

[mewachee]

first, ouch. I did not expect this much recoil. I am a recoil junky, but I didn't enjoy this at all. I noticed that Benelli sells a gel filled pad, anyone have experience with this product, or similar?

Second, the receiver doesn't seem to be designed to move the 3.5" shells. Jamming is a real issue here. The length of the spent shell is longer than the extraction port, it takes a good jerk or two to pull through the slot. Is there a simple fix for this, or is this in reality going to be a 3" gun?

In regards to the jamming, Im guessing your used to 3" inch mags. You have to get used to long shucking for the 3 1/2's. It does take a while to get used to-

 

[mewachee]

explain "long shucking." Are you talking about the pump action? I am very novice when it comes to shot guns. These hit me so hard that I pump automatically, maybe I just need to man up.

One of the things I noticed was with one shell, I would pump and the shell would shoot back into the chamber. Pumping again, and the same shell would go straight into the chamber again.

 

[chas08]

Sounds to me like you are not fully pumping the gun. Commonly called "short stroking". practice, practice, practice.

 

[mewachee]

using a spent shell, short or long, fast or slow, hard or soft, it does not matter. The shell shoots back up in the chamber, or it jams on the way out. It is like the shell is to long for the extraction slot. I find it very interesting that it builds enough energy to throw the shell back into the chamber without finishing the cycling of the action.

No other super novas having this problem? Could it just be this ammo?

Never noticed this phenomena with little brother's Benelli. We decided to "play" with some turkey loads on hand clays. OUCH! I knew it was going to beat the snot out of me, but I didn't realize it was going to do both nostrils at once!

I'd guess short stroking, though there is a chance it might be a legitimate malfunction. I have an 870 Express in 12ga that will fail-to-eject with low-brass (or aluminum) shells every once in a while.

Actually, thinking about your description, I'd guess short-stroking and technique problems. Probably induced by the recoil. Or does it also do it when just ejecting a live, unfired round?

I have shot quite a bit of 3.5 inch with buckshot out of my 12ga pistol grip nova. I have never had a problem like you describe. If I (really) slowly rack the action the shell wont have enough omphh to be ejected out of the ejection port properly. I really have to try to get that to happen. I am sure this would be typical of most pump shotguns.

 

[mewachee]

unfired ammo cycles as well as 2 3/4" shells do. I have shot 3" turkey loads out of this gun, not a problem short stroking.

In reality, 30+ hours later and my shoulder is still killing me. I ain't no wimp, I have shot a malfunctioning over/under, both barrels, with turkey loads at the same. That was nothing like this. So, I will probably go to the 3" black clouds, but gun should cycle factory 3.5" shells.

 

[mewachee]

I was thinking that I need to clarify, when the shell is ejecting, the open end is dragging across the end of the port.

 

[627PCFan]

Hmmmm, I handload Hevishot using Federal 3 1/2 inch hulls. I do know if I dont crimp down enough they are long enough to get caught in the ejection port, as its happened to me a number of times. Measure the final length of the spent shell and post it here-

 

[mewachee]

Loaded just over 3"

Spent just under 3.5"

I shot half a round of trap with a new regular Benelli Nova a few years ago. I somehow got a 2.75" shell jammed in the receiver and I had to stop and go get my 1950s 870 out of the car.

I sold the Nova at my next gun show. (And used the money to pick up a Winchester Model 25 AND a $100 30/40 Krag )

I may have been short-stroking it or something, but I have never had a problem at all like this with an 870, a Winchester, a Mossberg 835 or the Savage M67 20-gauge I grew up shooting.

 

[mewachee]

Solution:

Bad ammo. After closer examination, these lot of shells are extremely high pressure. I went into Sportsman's Warehouse, to find that someone else was having problems. The primers are cratered worse than I/they have ever seen. The rim of the shell is rounded from expansion, this causing the shell to slip off of the extractor early.

Have not heard back from Federal yet. I will start a new thread when I hear from them.

 

[627PCFan]

If your right about the overpressure from Federal Factory ammo, wow.

I have heard pressure readings from 209 Primers mean squat. Bulging brass might mean the action was not locked tight during firing?
