Default Inertia Drive Going into Battery Issues

Why don't inertia driven shotgun bolt heads rotate shut if you ease the bolt forward instead of letting it slam shut. I've seen this issue with the Browning A5, Franchi Affinity, Weatherby Element, and a few others. It seems to be inherent to the inertia design, to the point that Retay designed their Inertia Plus system specifically to address it. Now, I have not experienced this issue with gas guns, both rotating and tilting bolt designs. Can it be due to a weaker recoil spring on inertia guns? If so, is a weaker recoil spring required by design?

I personally have 3 Benelli shotguns with the inertia actions on them .2 M3 convertibles and a Montifeltro left hand action for upland game bird .I have yet to experience a issue with the bolt not seating in any situation I can recall .

Why do you feel the need to ease the bolt forward?

No problem with my Benelli but I don't ease the bolt forward.

Try (with an unloaded gun of course) tapping the buttstock on the ground hard enough to pop the action open, it probably will not go back fully into battery. Its a known issue on Benelli inertia guns. The typical senerio is say a bird hunter sitting in a blind. They bring the gundown to rest the stock on the ground while they wait, inadvertanly poping the action open a bit. Next time they rais the gun to shoot, they get a click instead of a bang. The solution naturally is to always let the action slam home, and don't put inertia into the bolt carrier by letting the butt hit the ground with enough force to unlock the action.

Yup according to BoBo the noise alone of racking the action is enough to scare away anyone wanting to do you harm. If that doesn't work just let 2 fly into the sky (especially in the city) and that definitely do the trick.

Op to answer ur question is to understand how inertia system works.

Most handguns also fail to chamber a round is lowered slowly.

That's why when you load a gun, you let the springs do their job.

Pull back on handle / slide and release.


Easy right.


Most cars steering is really heavy when the car is off.
This does not mean the steering system is broken.
It's just how it works

Went turkey hunting with a friend who has a Benelli M2 in 20 gauge. I have it on video. 2 clicks and the 3rd one went boom. He said it was dirty.Friend has a Montefeltro and I shot a M2 in 12 gauge while hunting in Mexico without a single problem. I love my berettas and v3.

I'm pretty sure I understand how it works, mostly. You're more than welcome to explain in case I'm missing something though.

This video explains it pretty well

As for out of battery

The other issue with most Benelli models is that it has a flat spot in the channel of the bolt body. If the forward force is too low, the pin stops at it instead of riding past it with speed. Once stopped at this flat spot, there is no pushing it forward like on most other guns. You will need to pull it back a little and let it snap forward.
Benelli fix it with its Easy Lock update, but only for certain model.

I was aware of this already, but ty. It still doesn't answer my question as to why there is more resistance when rotating the bolt head shut when compared to gas shotguns. Here's a video of the inertia system in slow motion btw.

That was the 2nd part of my post.

Once stopped at this flat spot, there is no pushing it forward like on most other guns. You will need to pull it back a little and let it snap forward.
Once it sits in the flat spot, you can't even push it in, thus it does not help even with extra power spring. It is more of a geometry of the channel cut for the cam than the inertia system, recoil spring, locking lugs etc.

So either if you try to ease the bolt close, or the bolt handle gets snag on something, the bolt can sit outside the battery prevented from locking due to that "flat spot".

It's not a big deal as pulling back the bolt 1/2" and let it fly forward will lock it right up, or even bump the butt on the ground will do the same. It is painful, however, for hunter after crawling around to spend time to check if the bolt is locked or not.

Ok yeah I suspected it could be the angle of the camming channel.

Slamming the bolt forward is part of the fun of semis........
