: rechoking a barrel

I recently purchased a remington 870 pump on the cheap. It came with the 26 or 28" barrel, what I am wanting to do is cut it down to a 18.5 inch barrel. The cutting it down is not the problem at all, the problem is I want to rechoke the barrel after I cut it down. All the local gunsmiths say they do not have the tools to do it. Some will say that there is no need to rechoke it but i would like it choked. Are there any vendors on here that do such work and if so how much? My other option is to buy a replacement barrel but the only ones that I can find are cylinder bore only I would like more options than that.
thanks
Jim

Kind of ghetto but have one install a polychoke or ream and thread for screw in chokes.

A vendor named guncat on arfcom is highly recomended for choke tube threading. I will be sending him my saiga12 barrel when I get around to pressing it out.

Do you want to "rechoke" it or have it threaded for screw in chokes? Screw in chokes would be much more versatile and cheaper. You shouldn't have to travel too far to find someone that can do it.

This.

He's done over a dozen Saiga barrels for me and a bunch of others. Frickin fast turn around too.
Real nice guy

Want to re-thread it so that I can use screw in chokes.

Another vote for GunCat. He is installing choke tubes for me on an 870 barrel right now.

There are shops that will cut in a new choke.
I beg the question that you said would be asked but didn't answer - Why?

The money you spend to get a choke cut in would pay for a replacement barrel on an 870.

The only barrels that I can find in stock do not have the option of screw in chokes. The only ones that I can find have a cylinder bore and I want more options that that. I prolly do not need more options I just want more options.

I have an old ('70's) Gun Digest and there's an article in there about rechoking a cut down barrel.

The guy actually took his barrel, heated it red hot and started hitting the muzzle with a hammer against an anvil. He then used a round file and dial calipers to clean it back up, then went and patterned it.

Sounds like a lot of work to me. Keep looking, you will find a gunsmith that can put screw in choke in there or maybe a precision machine shop

Another option would be a backbore job. It allows you to run slugs without worry, but causes the barrel to shoot like a modified choke.

Wow, thanks for the link. When I get this done this will be the guy I use. Seems to be a nice very fellow, was very helpful, and prices seem very resonable.
thanks

The question is why would you want a choke on an 18.5" barrel?
Just a waste of a choke. If you get one, do pattern and penetration tests and post them on PBB.

Remington has factory 18.5" barrels that come with fixed improved cylinder chokes(i.e. 870P) and also fitted for removable Rem-Choke tubes. You have a much more versatile weapon if you can change out choke tubes IMO.

You tell me.

I would like to test them to see if it is worth it. That is why asked for penetration and pattern tests.

I carry a shotgun most saturdays from October to the end of February (minus a month for deer seasons). I carry all type, shapes, and sizes.

I know when I am serious about killing something, I take a long barrelled modern shotgun. However, most of the time I am carrying 100 year old double barrel. I enjoy the additional challenge of taking game with a lot less advantage. When I am in the mood to shoot, or get into an area with grouse - I am breaking out the big gun.

I do pattern and penetration tests all the time with my guns.

I have a 20" barrel double barrel that I use in cowboy action shooting. Both barrels are cylinder bore (no choke). It is worthless to hunt with.
If you use a load with a good cup wad, you can get marginal performance. If you use one without a cup wad, you might as well be shooting a bb gun with a blindfold on.

Well if nothing else, it looks badass.

If you're going to have an 18.5" bbl on a shotgun, why NOT have a choke, unless you are shooting slugs?

XX Full Turkey tube. @ 30yrds I had a 9-10" pattern. Out of an 11" barrel.
I spent hrs shooting clays sat. So yes. I'm happy

But to be honest, I know zero about chokes really

If I whacked off the barrel on a shotgun for home defense, I would see no reason to have anything in there for choke. Shoot some #1 buck through there and see how it shoots at 30 feet. I bet you will get plenty of kills. Save your $$.

I can use this in 3gun open division though with chokes. My next one is going to be suppressed

I bought a used Benelli M2 with an 18.5" barrel. It has the choke system in it, and patterns fairly tight with the full. I got to playing around with it, and I for Christmas got a Rhino extended choke for it to see if it will pattern well for turkeys.

I'll post pictures on the pattern in another thread, when I go to shoot it. :smokin:

If you can run some through the chronograph, then compare with a longer barreled gun.

I always did "soup can" penetration tests. Specifically when working a load for my muzzleloading 10 ga. Work a powder, wad, and shot combination that would hold enough a pattern to put several shot into a "tin" vegetable can and penetrate and at least the dent the other side.

I have never been motivated enough to see the ballistic difference (pattern vs. velocity) between short barrel vs. long barrel. I suspect you lose enough performance at some length barrel to make it not worth it to go that short.

On a side note, this spring we are tearing down my friend's old home place. I want to do some ballistic tests shooting through the house with different rounds. Get some real life data what penetrates sheet rock, exterior siding, etc.

i'm sure there is a point in barrel length where it just falls off. I'd love to be able to shoot up a house. Would make for a very cool study.

AFAIK Remington doesnt make a 3 1/2" 12 gauge 870 barrel shorter than 24" I know this, because I wanted a 20" one for mine. I know you can use the 3" barrels in the magnum receivers but I wanted a 3 1/2" chamber and changable chokes for turkey blastin. I had some random clown I found via google do the work and cant say I'm really happy with it. Screwing the choke into the last few threads has alot of resistance and I can feel a slight edge from the bore of the barrel to the choke tube. If I like guncat's work on my saiga I might get him to un-fuck my 870 barrel too.

Lets not forget that a choke on something along the lines of a Rem 870 Tactical can be used for something besides patterning shot.

That is another reason I wanted it threaded.

I will be getting a 18.5" barrel back from being threaded for Rem-Chokes by GunCat this week and will do some testing with different 00 buck rounds and choke tubes. I have Improved Cylinder, Modified, and Super Full Turkey choke tubes. I may not be until next week that I can have some results however.

My 870 is more than a HD gun and I would like to see how it shoots different loads in conjunction with different barrels and constrictions. I have a 28" Vent-Rib barrel and the 18.5" barrel, both with removable choke tubes.

Any updates on the barrel. I have not sent mine off yet but will soon. got any pics
