It's a single shot NEF pardner I picked up used I primarily want to use OO buckshot in close. It has a mod choke. I just want to raise the pattern up a tad.
Fired from 15 yards...red dot was point of aim.
I did find a couple of fixes from other forums. One was bending the barrel the other was steel wool in the barrel (see below).
What's the HB members idea's?
-----------------------------------------------------------------------------------------------------------
Subject: Re: Bending the barrel?
I made some cradles for each end of the barrel by drilling a barrel diameter hole in a piece of oak, then cutting the piece in half bisecting the hole. Place a half under each end of the barrel, then use a large C-clamp near the middle with another cradle positioned on top of the barrel to protect it from the clamp. Tighten the clamp until the barrel bends some, it will flex back some, so you'll need to bend it past what it will eventually stay at. You'll need a very stout work surface, I used a steel I-beam used for straightening car frames, but a sturdy work bench or maybe a 4x4 would work, too. I used shims under one end of the barrel cradles so I could control the exact amount of bend, tightened the clamp so the barrel touched the work surface each time. For shims I used pieces of ΒΌ" plywood, veneer and then sheet metal until I got the amount of bend in the barrel that I wanted. I just used a 4' steel ruler on top of the barrel when checking the bend, you can see the gap the bend creates.
---------------------------------------------------------------------------------------------------------
Put an empty shotgun shell in the chamber.
Get a 3/8 dowel rod and 1 inch from the end of the rod cut into it at about 45 degrees with yore pocket knife , don't remove the shaving, leave it, now do the opposite side.
Move up the dowel rod 1'' and do it again until you have 3 rolls of notches.
Buy some very fine steel wool and wrap around the notches on the dowel rod.
Chuck the dowel rod into a electric hand drill and spray the steel wool with Liquid Wrench and slide it back and forth up and down your barrel with the drill running. After about a minute and a half stop and clean out the barrel.
This should straighten up any pattern problems any shot gun may have.
I learned this at a sporting clays forum. Hundreds of members tried this and it vastly improved there shotguns accuracy.

Wolfkill, Just a few questions here.....Is this for coyotes, deer, or self defense? If it's for hunting can you mount a scope on it? If it's a ribbed gun get a set of adjustable turkey sights that clamp on the rib. If it's not a ribbed gun I think there are ribs out there that you can install. By tapering the rib bases you could adjust point of aim. Some of these are sweat on but I think you can get epoxy applied ones too.
Where does it shoot with bird shot? You might try a different brand of buck too.
Bending the barrel just seems a little drastic. I do know though that it was often needed when Cutts Compensators were installed in the old days. RD

Raise the rear sight?
Different brand of buck shot, need more velocity....
Barrel bending should be done as a last-option-all-other-options-already-tried thing.

Primarily used for coyote in heavy brush. I shot some 3" mag slugs and they were even lower (6" at 15 yards) and out of the question to use.
It's a cheap beat around gun that gets broke down and hauled around on the dirt bike or the one I take out in snow and rain.

Wolfkill. Don't bend the barrel.
Think of the butt stock of a shotgun as your rear sight, As a rifle, if you want it to shoot higher ,you move the rear sight in the direction you want the impact of the bullet to go. It is the same with a shotgun. You move the butt stock in the direction you want the cenrter of the pattern to go. Therefore,the drop at the heel of your stock need sto be less
Now as to how much:
Set up a 3 ' x 3' paper backing at 16 yds, put a 1 " black square on it inthecenter.
Take three shots at it with your shotgun. Bring the gun up and as as you aquire the square ,fire. Like a shotgun, you don't want to do a lot of aiming. Shotguns, you point, not aim.
If you are consistent, you wil get all three shot patterns pretty much superimpsoed on each other.
Measure from the approximate center of the shot pattern to the 1 " square. For every inch you want to move the pattern,the butt stock must move 1/16" in that direction.
You might try adding one of those leather padded cheek pieces. Don't know if that would help or not

Try adding height to the stock. I've seen lace-on cheekpieces, never used one, but you could tape on 'most anything to give it a cheap try. When you mount it, that should raise the muzzle.

Oh heck...I forgot I have I a spare NEF rifle fiberglass stock/forearm I put on for giggles once but took it off once I realized it raised my cheek off the stock and would cause it to shoot higher.
D'oh...I got too many accessories laying around. God knows how many times I've run across something new in a package and didn't know I had it.
When I die I suppose I'll be one of those guys that they keep finding firearms, ammo, and accessories stashed in the walls and ceiling for six months after the funeral  .

Just raise the comb on the rear stock. Buy one of the strap on rear cheek pieces.

Bend? generally I just use the butt of the gun. lengthen the bottom a hair, it will work.

you could put a bit of pitch into the butstock if you need to.
loosen the but pad put a quarter under the bottom of pad near the bottom
screw if it raises up the shot enough then you know that is the amount you need to add to the bottom or take off the top.
adjusting the l.o.p. can change how low or high a shot hits compared to p.o.a.

I bought a break open single shot in the '70's & couldn't hit a bull in the butt with it.Some club members told me to check the bulletin board at another range for used shotguns ,saw an ad for 2 Remington 870 Wingmasters in 12g & 20g with trap & skeet barrels that belonged to a deceased member,contacted the widow and bought them both for $225 with some reloads.I sold the 20g after my son outgrew it but kept the 12g that I'm still shooting it has had many thousands of rounds fired thru it,needless to say it's very accurate. I've used it for mtn & valley quail,grouse,pheasants,bandtailed pigeons,dove & rabbits mainly with the 30" full choke trap barrel plus I've won cash & meat with it for over 30 years. My advice: sell the single barrel & buy a Rem 870 new or used you won't be disappointed as there are many different barrels available & you don't need to be a gunsmith to tear it down in fact parts are available in out of the way places since it's so popular! Another retired le friend of mine owns several O/U Brownings but said his Rem 870 is still the best shooting shotgun he owns. Last edited on Sun Jun 8th, 2008 03:59 PM by sako06

I just remembered I have a gun like that. Just get used to it, or go with the butt adjust idea.

Late entry, but I'm with the don't bend crowd. One cheap solution is to glue a small block of wood to the rear of the barrel, just in front of the breech. Bench pattern the gun with three shots, using the block to align it just under the front bead. Sand the top of the block and repeat until you have a "suitable" shot distribution. Carefully measure the height of the block, and replace it with a bit of metal shaped to your liking, and sweat it in place. Trap shooters use a sort of rear sight to help align the barrel with the eye when mounting the gun, and never look at the sights again after "pulling" the bird. The mount is the key.
But get the 870 anyhow.

Being fairly unskilled at gunsmithing as I am, I'd just aim a little higher with that load or use one with a heavier buckshot charge.
Back in the day, we used to have to qualify with our short-barreled 870 "riot guns" and keep all the OO buck pellets in the black at 25 yards (and all the rifled slugs inide the 9 ring or better at 50 yards) on a standard B27 silhouette . One pellet out - no qualification. That took some practice and a number of guys didn't pass on the first go 'round.
We also had to walk 5 miles to work in 10 feet of snow, leap tall buidings in a single bound, change the course of mighty rivers, bend steel in our bare hands, all while fighting for truth, justice and the American way.
Nostalgia - it ain't what it used to be.
