If my SBE is having trouble ejecting spent shells. Is this the correct spring that I need to put in.......

 

Wolff Recoil Spring Benelli Super Black Eagle 25% Extra Power

 

I want to make sure this isn't for shooting heavier loads before I buy it. Is $12 a good price of can I get it cheaper and if so where?

 

Actuall it is not mine but a friend of mine whom I can buy if "right" from b/c he is sick of screwing with it. All he has done to it is clean it good a few times. The warranty is up now and I am considering buying it, if I think I can fix it. :D

Here is a very comprehensive article I wrote about cycling issues with SBE, M1, and Montefelro Bennelli's. The Wolff recoil spring 25% Extra Power is a great replacement spring. All of my Benelli's have them, most of the guns I service request them. Remembering, these are hunting guns. The 25% extra power spring may not cycle 7/8 oz low brass shells. This becomes a more of a issue when temperatures lower and shooting directly overhead shots when the rotating bolt faces the forces of gravity. Following the below instructions will eliminate cycling issues with rotating bolt lockup.

 

 

Benelli M1, SBE, and Montefeltro Recoil Spring & Maintained tips.

 

 

My experience with Benelli Autoloaders is quite extensive. I purchased one of the original Montefeltro’s imported by H&K and have worked on and performed year end maintenance on over 200 guns models listed above and the Nova.

 

I’m sure everyone knows how to “field strip” your gun, I will not cover this however I will add what may be of value from my experience. What most Benelli owners do not know about the gun they own is, the vital component listed as the recoil spring and the recoil spring tube. This will be the focus of this writing because it is not covered in the Benelli owner’s manual. With the knowledge and understanding of this maintenance and process, the problems experienced in cycling issues could be completely eliminated. It is vital that your recoil spring maintenance be performed on a yearly basis, the exceptions would be low usage or submerged gun.

 

Removing the Butt Plate requires a thin shaft Philips screwdriver with a number #2 head. Apply oil to the Butt Plate screw holes before inserting the screw driver. This will minimize the damage to the rubber. Remove Butt Plate. Insert a 13mm deep socket in the back of the stock and remove the stock retaining nut, this nut will need to be torque to 22 lbs upon assembly. The stock assembly and drop change shim will come off. To remove the recoil spring, the stock retaining nut SCREW will need to be removed from the recoil spring tube. This will require a 17mm closed end wrench. Older Benelli’s will not have the nut attached to the stock retaining screw; this will make the process more difficult. To remove the stock retaining nut screw, my experience has been in most circumstances heat will be required to address the locktite which has been applied to the screw from the factory. Place the receiver assembly in a vise just tight enough to hold the receiver be careful not to crush receiver. Protect the receiver to eliminate damage. Heat the stock retaining nut screw near the recoil spring tube with a Bic type lighter for up to one minute. This is all I ever needed to slacken the locktite. Then place your closed end wrench on the nut and loosen. Care must be taken when removing the screw the assembly is under pressure of the recoil spring. The recoil spring ready to be removed and the recoil spring plunger. Upon assembly do not use locktite, this processed should be performed annually anyway.

Concluding, the recoil tube should be cleaned with gun scrub and a 20 gauge wire brush inserted through the tube. The recoil spring should be cleaned as well. My experience with the factory recoil spring has been less than desired. I have replaced factory springs after one year on M1’s model number 11045 serial numbers M400240 and M400239. The original Montefeltro springs seemed better, lasting 10 years. I replace the recoil spring with Wolff 25% extra power spring. Keep in mind these are hunting guns and do not shoot low base 7/8 0z shells. Wolff 25% reduced power spring works well for light loads. You will know when your spring needs to be replaced when the bolt assembly does not rotate to the closed position after shooting the first shell, when your gun is properly maintained. This failure increases when shooting in cold weather and shooting directly overhead, when the bolt faces the force of gravity. Assembly of the recoil spring requires minimal usage of synthetic spray lube, just enough to lubricate and protect metal. Excessive oil will collect more powder residue. Synthetic will minimize congeal at low temps.

When reassembling the gun it would be helpful to install your trigger assembly, this will make the alignment of the stock easier. The bolt assembly should be kept clean. I use a few drops of Break Free inside of the receiver assembly on the bolt rails, this should be all the lubricant you will need after cleaning the assembly with gun scrub. A “dry” clean magazine assembly, dry meaning no lubricant, will create the same symptom of the bolt assembly not rotating closed in cold weather as well. This cost me a double on Canada Geese this year because I was to lazy to field strip my Benelli and lube it properly when encountering cold weather. The field striping and lubricating noted above can be performed in a few minutes after a few repetitions.

 

I am hopeful this summary may be helpful. Performing complete and well timed maintenance will go a long way towards keeping your Benelli in great operating condition. Nothing is worse than a semi autoloading shotgun that becomes a single shot. I wish I would have had this information when I purchased my first Benelli.

 

Drop me a note if have any questions.

I have a Supersport and the S/N starts with F297.... If I shoot almost only trap with low brass light loads, what recoil spring should I use? Should I stay with a Benelli exact replacement or get a Wolff?

 

The gun is completely stock but probably has fired at least 30,000 shots. I assume I need to replace the spring from time to time to keep it working well. I have started to have the problem were when the bolt closes, it doesn't turn bolt and fully seat and leads to the Benelli click.

Well with that many rounds it probably wouldn't hurt. As always, cleaning and oiling is imperative. The Benelli click I have found is mostly unrelated to a used recoil spring. Many times it's actually a battered extractor cut on the barrel. Many people get too wrapped up in whiz bang springs and accoutrements while overcomplicating the obvious. Often this little radius is overlooked. It gets pounded every time the bolt slams shut by the extractor. With time a burr can build up and when the bolt tries to close the extractor can get stopped or delayed by this burr. This keeps the bolt from getting to complete battery and thus misfiring creating the Benelli click. Judicious use of regular or diamond needle files on this radius can go a long way to curing this problem. Just make sure the radius and curvature of the cut is kept.

Thanks for the info. Where is a good place to order a stock replacement spring and how do I know I get the right part number. The manual doesn't have part numbers and the online places offer Benelli parts with a S/N break but my S/N doesn't look like it matches when I look on 3rd party web pages.

 

I do keep the gun clean and oiled so maybe it just use that cause a flat spot.

No, go back and look at the post. Put down the receiver and trigger assembly and bolt (leave the bolt alone). The barrels extractor CUT radius may be where the problem lies. Please do not be ashamed of not understanding this or even it being out of your league. It is for most people. I'm sure that if you saw it done even once you would say "WOW" that was simple! Brownells has the replacement spring. The Benelli part number is 60691.
