Hello Chaps,

I recently asked Remington to let me know what the standard length of a forcing cone was on a 870 and rec'ed the following reply:

Dear <snip>:

Welcome to Remington Country!

Forcing cones are featured on our sporting models. Our Model 870 Express is a field grade model shotgun. A forcing cone will not greatly improve or enhance the performance of a field model shotgun.

Thank you for your interest in Remington products.


Does anyone know if this is actually correct and if so why?

Regards,

It's my understanding that forcing cones have not changed. When the new plastic shell's came out they used the same forcing cone as before even though more is needed for the plastic. If someone knows different please post and I'll admit being wrong. If the barrel on the Express is not too thin, extending the forcing cone will help some with recoil and improve the pattern a little.

Hmmmm..

No forcing cone at all?????

No improvement on a field grade model but they have them on sporting guns????

The 870 does have a forcing cone but a very short one. The answer about the field and sporting guns is contradictory and frankly ridiculous.

There is plenty of barrel to extend should one desire. That's how Vang makes his living.

Maybe Big Green needs a little more knowledge in the answer department. Sheesh.

I too cannot believe the answer received from Remington, hence my post. I've already asked them to explain themselves and will post their response ( usually takes a week ).

FWIW my reason for asking the question was to establish how much extra I needed to ream in.

Somebody at Big Green isn't earning their pay,
but we knew that already.Since this is a family BB,I won't say what I think that Remington Spokesperson is talking out of....

UK2TX, length is oft debated, but a good one seems to be 1 1/2-2 inches.Polishing is essential, concentricity is crucial, it takes the right jig and tools to do it correctly.

TTBOMK, the only breechloading shotguns EVER made w/o forcing cones were a few old Brit Waterfowling shotguns with no chambers per se, and used only with very thin, special brass cases carefully handloaded. Very rare, and modern loads seem to surpass their performance, good for the time.

One thing about long cones, and I'm an enthusiastic user of same. While an excellent mod with little/if any downside, they're not mandatory for good performance.Wildeyed but semi educated guess, they cut recoil 3%, and improve patterns by maybe 5-10%.

All 870's and other modern shotguns have forcing cones. The dufuss at Remington probably isn't quite sure from which end the shot load exits. He or she probably does know which end of a golf club to hang on to. Duh, welcome to Remington Country.

To prove the above statement, take a look through the chamber end of a new Police Magnum barrel. They have reamed the poor thing to oblivion. The forcing cone reaches half way up the barrel. (OK, I exaggerated a bit) Why would they do this if it doesn't enhance the performance?
Could it be because Vang Comp and other custom gunsmiths have been doing it for years?:confused:

Nash Buckingham was doing experiments with long forcing cones back in the 20s and 30s, and mentions he wasn't the first to do so.

As to why Big Green hasn't caught on to a longer cone, despite the myriad reports of improvement, I chalk it up to inertia and reactionary thinking.

I am pleased that at least some 870s are getting good cones, maybe it'll spread....

Doh!! I looked down all four of my 870 barrels, they all have forcing cones:rolleyes:

The forcing cone is the part of the barrel that is always the dirtiest and most difficult to get clean. If you look down the barrel from the breech end while holding it up to a light source the forcing cone is the dark area immediately forward of the chamber. It appears to be a dark band because of all the plastic fouling that builds up there:D

Poor Remington, what IS happening to them?

The latest responce from Remington :


When our engineering department designs any particular model, all variables or enhancements are taken into consideration.

In our Model 870, the initial design of a barrel is tapered as in a forcing cone design. We found that a "lengthened forcing cone" such as is featured on sporting clay models did not improve accuracy or performance. As there was not a significant factor with this feature, we did not include the feature.

Have a good day!

What kind of an answer is that? The "initial design" of an 870? Did you tell them you had an "initial" model? Who are these dolts?

Redirect, Your Honor...Remington: do you ream forcing cones in your 870 barrels? A simple yes or no will do...
