I am having a single barrel nef threaded for rem-choke and plan on shooting Winchester Longbeards since these are already protected by a resin I was just wondering what yalls opinion is on having forcing cone lengthened will it help or is it just a waste of money..

i dont have any experience with that gun so maybe not apples to apples here. I had my SBE2 forcing cone done and it did make a difference in my pattern performance in a positive way. I am going to get my 20 guage done as well. You will find mixed reviews for doing it on OG but from the few I have personally seen done they all had better performance after it was done.

X2 - My SBE2 has been done and after turkey season my M2 20ga will be sent to have it done.
I had Sumtoy lengthen the cone in a browning inv+ barrel. I hadn't shot the barrel previously, so I couldn't compare it before modification, but it patterns good. It also took a little "snap" out of the recoil. Definitely happy with the results. I have heard mixed results to having the forcing cones lengthened, I think I read that it usually helps more with lead shot than htl? I know it does cut down a little on recoil, which is a nice benefit in a light gun, without the increased noise of a ported barrel.
What do you mean by mixed results do you care to elaborate.
Most every turkey gun I have has elongated forcing comes. I've never once seen it do anything but improve a pattern. How could it make things worse? Many guns nowadays come w this already done
forcing cone work is done to reduce recoil...you are flipping a coin to see what happens to your pattern. usually nothing drastic. but it does not in all circumstances improve the pattern and in some instances it goes the other direction.
Had the forcing cone done 25 years ago, other thing was to have the "bore polished" to improve my paterns. Can't say as to the improvement, But did this as part of a "Turkey Gun Build" when I bought the gun as a dedicated turkey gun and talked with our smith team at the time, gun was built as a "build" for our gunsmith team to show off their "capabilities" work as I was taking it around to all the turkey seminars I was doing, they also had changed out the butt stock to cheekpiece version, did a cantilever bbl and then the gun was dipped, scope and mount back then too, custom choke was tested for it. Since then the only change I made was adding a Remington 11-87 ShurShot Camo Synthetic Stock & Forend to it.
I added a pic of the original model and what it ended up as :)

I was under the impression - maybe incorrect, that you shouldnt do forcing cones on Benelli due to chrome lining of the bores?
Rob Roberts does them all the time . I've heard it's difficult to manipulate a chrome lined barrel when it comes to that stuff because it's harder..... but not impossible .
I had the forcing cone done on an 870 about 25 years ago. With the ammo available then, it definitely improved turkey patterns. With the ammo available now, I don't see much improvement. I doubt it will help with longbeard xr ammo. Honestly, find the right choke and it doesnt need any help.

Idk what the theory behind it is now but I started doing this in the 80s. Back than Mark Basner was the shotgun man. The cones were opened not for a reduction in recoil, it was to improve pattern. You did lose slight velocity though. Since than I've had and still have multiple guns that way. No way it could ever hurt having a gentler entry into a barrel as opposed to rattling its way to a start.
I've never seen things get worse. When Mark did em for me I'd send him barrels. They always improved.
Now as I said I don't buy guns now without it so I can't compare before and after like that. Many guns come elongated though when turkey specific or just wing shooting type guns also have em lengthened.
Ithaca, Browning, Mossberg, Fabarms to name a few off top of my head
I agree...it can improve the pattern, and we do it in hopes that it will....but it don't always....and that is proven. Ive seen a few barrel guys claim that they gurantee they can make it improve . Maybe they can, maybe they cant. I actually just took a chance and let a different guy do a second barrel for me. I cant tell the difference between his work and my original barrel other than the fact that he did it and had my barrel back to my house in about 10 days.
Prob has something to do w shells too. W all the technology today idk what all the factors involved might be. Some of the wads hang on til a bit down range, the buffering stays intact and breaks upon hitting choke, even dif buffer types. Than add TSS, stuff is supposedly really hard, less likely to deform. Bet all those variables come into play.
I shoot lead still
I sent a 870 several years ago to Briley to lengthen the forcing cones. Patterns got worse for me. I wouldn't do it again for sure.

Works well for me and I use LongBeards exclusively. :camohat:
I have been told by several shotgun barrel guys/Gunsmith that lengthening the forcing cones; shortened the shot-string. I have done it myself to a bunch of barrels. All of them with positive results for sure. Also done it to chrome lined barrels.
Browning/Winchester has back bored barrels which is essentially the same thing, as I understand it.
Have a good one
