Benelli M2 cycling issue

Postby MOdnj » Fri Oct 19, 2012 2:41 pm

Buddy has a brand new M2 he just sighted in for the first time. Shoots great, ejects empty and cylces in new round, but won't fire it. Like the hammer doesn't recock during the recoil process. Can't imagine a slug not having the inertia to properly function the action here.

My brother's suggestion was to drop the trigger group, degrease everything and then oil it all back up before reinstalling.

Thoughts?

A thorough cleaning is the first thing I would do.

Agreed, clean first.

It seems like the gun may not be fully chambering the new load, meaning that the rotating bolt head is not fully engaged. This is commonly referred to as Benelli Click and tends to be present in brand new guns that havent been broken in yet. My suggestion would be to continue shooting the gun lots. Those sharp unworn edges inside the chamber haven't had a chance to smooth out yet w/ use and could likely be the culprit.

Why is he breaking it in with slugs?

If it is a new gun there is a good chance the factory packing grease is the culprit. Pull it apart, clean EVERYTHING then put it back together dry.

Why not? Good powerful loads are great for break-in, maybe he had a bunch laying around.

Since he is sighting it, I am guessing it is a slug gun?

Lube it up sloppy wet with Break Free CLP. Never run a gun dry. Machines need lube. I have fixed several guns that would not work in the field with a few squirts of the little CLP bottle I carry in my choke tube case.

Some lube, yes. Definitely not sopping wet. If you hunt in any kind of inclement weather, that excess lube will get thick and collect dirt, un-burnt powder flakes which will have potential cycling effects.

I don't run mine completely dry since we don't get extremely cold temps in Western Oregon. However, I typically have a drop of CLP on each rail and the underside of the bolt.

X2. I run mine dry in cold weather. Early season may have a drop or two on it, that's it.

The bearing/friction surfaces are so small in the Inertia guns you can run them dry. I have for the last 10 years with no noticeable wear and no problems

On the Benellis you can look into the slot behind the bolt and see if the hammer is cocked or still riding up behind the bolt. Is he shooting it from a Lead sled? if he is it will not cycle completely and will give you this issue. the benellis must move during recoil to function. Also my M2 tactical will not cycle some slugs, buck shot and target loads with the 18" barrel on it, with the 24" barrel it functions fine. try some hotter loads if the trigger cleaning does not resolve th eissue.
