Thinking of sending a barrel off to have the forcing cone lengthened after the season.

Anyone have this done? Does it really make much difference?

I'm still on the fence about it and skeptical that it will make much of a difference. Im currently happy with the way my gun shoots and patterns. It doesn't cost that much to have it done so if it makes a little bit of a difference I'm fine with it.

Have two 870 barrels, both 28 inch, one bone stock, one with forcing cone lengthened 1.5 inches.

With the same choke, shooting 00/000 buckshot at 40 yards, the stock barrel on average patterns 1-2 inches tighter with the stock barrel than with the long forcing cone barrel, with more pellets in the center.

Didn't do anything for me.

YMMV,

I'm reading alot about it. Most people state it makes minimal difference if any. I have a problem with always jacking with stuff even when its not broken. Still on the fence about it....

I've done it to a bunch of different shotguns.
It helped all of them that I did
The f cone and bore should be polished also
to make it work right.
This works better on the older guns that
were bored in the old way. Most of the
never ones are backbored and would probably
benefit more from experimenting with
different brands of the better ammunition
I don't think I have a 12 and 20 reamer any
more. I'm sure I still have a 10 gauge but
not any of the flex hones

You might find out what the standard forcing cone length is on your shotgun. Today, competition shotguns have forcing cones as long as 5". I have three K-80's that have long cones from the factory. I too have sent barrels to have the cones lengthened. Some of my older Berretta's were done. The only major difference I can tell is on the recoil. When the charge jumps out of the shell, rather than say a standard 3/8" cone which will create more felt recoil, the charge is squeezed down over a long cone which produces less felt recoil. This I know works. Years ago I was shooting upwards of 40K shot shells a year. At that time I could tell the difference. Today, approaching 75, it's a different story.
If you decide to have it done, make sure whoever does it knows what they are doing. You can mess up a barrel real quick if they don't know.

I have forcing cone reamers for .410 ,20 ga. 28 ga 12 ga. . Plus a chamber reamer for .410 to make a 2 1/2 chamber into 3 ". Also have the flex stones and the oil they say to use . Every shot gun i have owned got reamed , and it helped on all patterns .Brought the fliers in 2-4 inches.

Well if extended forcing cones made such a difference why wouldn't every manufacture send them from the factory with the extended cone? Or atleast your top end guns.

I do my research before making decisions. That includes alot of online reading from real world experience. Alot of what I read is people stating no difference to very little difference in pattern test.

Leon confirmed that. Everyone else that says it makes a difference does not have any support to back it. Frio only states he felt less recoil.

Not trying to jump in the debate, but the A400 comes with a longer forcing cone. Just FYI.

Backboring on a lot of the new shotguns helped, by having more open bore diamenter. Then the forcing cones were not as steep and they didn't squeeze the shot and wad as much before entering the bore.

Is there a particular problem with the patterns your shotgun throws?

Then do the full research and call Rob. See what he says about it. If you've done your research then you know the right questions to ask.

Leon also tested using 000 buckshot... kind of a limited sampling to determine it makes no difference.

Like i said, I'm not calling rob, he's the salesman. Of course he will tell me how great extending the forcing cone is. Its an easy job to do and easy money in his pocket.

I am considering sending my gun to him this off season for a cerakote job. While its there I'm considering him doing the forcing cone.

True, but I am also doing online research from other forums and articles. It seems like most peoples consensus is it makes minimal difference and you still need to find a particular load that your gun likes. Further articles state that is why the majority of shotguns do not come from the factory with extended forcing cones. Through the manufactures R&D they could not locate any sound conclusions or findings.

I feel like the forcing cone theory is similar to the after market extended chokes theory. Its just a gimmick.... with that said I shoot extended chokes and am still considering the extended forcing cone when I send my gun off to rob roberts. I may just have to play around some more with the patterning board when it gets back.

Sounds like you had your mind made up before you even asked here. Good luck with whatever route you take.

For a bird hunting gun, you will not kill any more birds using lengthened forcing cones. Time at the pattern board with various loads and chokes, at the ranges you intend to shoot will show you the patterns you are looking for. Practicing until you can center your patterns where you want them is almost always the best answer to improved performance from a shotgun. I have seen just as many wing shooters beat the piss out of the birds with bone stock shotguns and cheap bargain priced shot shells as I have guys shooting top of the line stuff blame deficiencies in their gear for their lack of prowess.
Spend that forcing cone money shooting the snot out of that shotgun in the off-season.
