20ga. to 38 spl.

[Shingle]

I ordered a 16" rifled barrel insert to fit a hatfield 20ga. shotgun. Can anyone give me tips on how to secure it to the shotgun barrel?

[Outpost75]

Normally these are a drop-in fit, intended for intermittent, temporary use, so they may be removed when you want to use the shotgun. Some need to be removed to knock out the fired case, if they don't have an auxiliary extractir which is activated by the shotgun extractor.

I recently bought a 16" 20 ga to .45acp adapter, rifled. Came with 2 rubber o-rings.

Works like a charm, but you do need to be able to remove it if a cartridge gets stuck.
And from my prior experience with shorter adapters, they will get stuck.

Find a case that fits the shotgun broken down. Make a cloth sleeve and slip the insert into that inside the case. Pull it out and use it when you want it.

The only thing I plan to do on mine is mark it for accuracy where it should be clock wise. I'll probably use a black sharpie at first. Trying shots at 3 oclock, 6 oclock, 9 oclock and 12 oclock. See what comes closest to where the bead points. Then as long as I index it the same it should maintain reasonable accuracy.

To me one of the big advantages of this system is that it gives an already flexible system even more capability.

Securing it into the barrel would be going the wrong direction. And if we misunderstood you, and you meant secure it to the OUTSIDE. Well I have no clue how you would do that, or what it would do to handling characteristics.

Worst case scenario a piece of thin walled 1" pvc with a cap on one end, and a threaded plug on the other. Drop it in and screw on the end. Then bubba the PVC to your hearts content.

I've thought of these but unless your shotgun has adjustable sights you'd be better off where you started. IMO.

I've got a set of adjustable turkey sights that clamp on the vented-rib.

Drillings have sights the pop-up when the rifle barrel is selected.

A manual version of folders inleted into a vent rib shouldn't be too hard to install.

I'd greatly appreciate you sharing where you purchased your insert.

I have no idea how the inserts for American shotguns perform but the Sempert-Kreighoff einstecklauf I have in my Thieme & Schlegelmilch drilling is easy to remove and install, repeatable upon removal and re-installation and is accurate. Mine always extracts as the extractor on the einstecklauf is actuated by the shotgun barrel extractor. Good enough for head shots on squirrels at 35 yards with open sights. They're a bit of a pain to sight in as they adjust in an "X" rather than vertical and horizontal but once sighted will remain so.

Landy Ebay, PM sent.

[Shingle]

I got it off ebay.

If i can get it to shoot good,I plan to drill and tap the rib to put a tiny red dot mount.

Well my liner came in and he sent me a 9mm instead of a 38spl. What a stroke of luck im set up for 9mm not 38 just ordered it because thats what was in stock. I tried it in several shotguns, the hatfield was the accuracy winner now i cant find one anywhere. I was impressed with the accuracy with just a bead sight.

I have the 5 inch rifled 38 Special insert from Gun Adapters and can keep them all on a paper plate at 25 yrds with just the bead front site.

I would like to find a gunsmith who would install adjustable sites on my Winchester 37 for a modern day " Trade Gun".

[Shingle]

I drilled and tapped the shotgun barrel and put a one slot scope base that holds a TRS-25 red dot. The gun holds groups the size of a coke can bottom at 50 yds. with one certain load, others it doesnt do so well. It's a interesting beater gun to keep on my side by side. The other choice was a .380 HI-POINT carbine which I still ordered anyway,but single shot pistol caliber carbines have always interested me.

Not much experience with adapter tubes but have put sights on many shotguns. For ribbed barrels
the one piece ramp sight for Savage 340 series is perfect fit, rib is easy to D&T for 2 screws in this
sight. I have used a lot of different rears, just put in vise and remove the dovetail, drill 1 hole in
tang and D&T to rib. Plain barrels have a lot more options. The bead sight can be remove and hole
can be redrilled for 1 of 2 holes you will need for front sight. The sights of the older Rem 700s
make a good match for single barrels. The older sight has a steel base that is easy to solder on
with low temp solder. The Rem 700 sights just need a little Dremel work to mate radius of your
barrel. Another option is Marbel dove tail blanks, made of steel can be attached with screws or
soldered. Used for front and back they will accept any sight with 3/8 dovetail. I have Rem 700
rear sight on sawed off A5 Browning and Williams ramp on front with Marbel Patridge blade. They
are low temp silver soldered on and take the stress of recoiling barrel for 40yrs. A word of caution
I would not recommend drilling and tapping rear of shotgun barrel, unless over breech area that
you don't have to drill clear through into bore. Won't make any difference for auxiliary barrel, but
may blow back sight screws out with use of Shotgun. I have seen many blow off, acts like a soft
plug on pressure. You hear guys brag about doing this until rear sight takes them between the eyes.

tranders, IMO you can do better than that with slugs or buckshot. With the bead. I'd try the marking method mentioned above.

Not so much. https://www.bing.com/videos/search?q=shotgun+inserts++youtube&&view=detail&mid=8C986E05B73AFCAE16478C986E05B73AFCAE1647&&FORM=VDRVRV

I've shot lots of .45 acp from my 20 gauge single. You get the feel of it pretty quick.

The insert the guy is shooting in above video is an older Short Lane. The newer ones have a 'scallop' for easier case extraction. All excellent quality.

Chiappa is selling 8 adaptor sets separate from their M6 over under folding survival gun. Retails for $221.00+-. The machining is impressive. Very clean. They are 8" long, rifled for cartridges and .410/.45 colt. 20 ga smooth bore. The set for a 20 ga break open only has 4 calibers.

Tim Ralston of Ralston armory first developed a multi caliber revolving survival gun for the air force. The barrels were machined in the cylinder and remained stationary so you only fired one caliber at a time. The cylinders were too expensive to mtg. So he switched to shotgun inserts. They originally retailed for $447.00 made from chrome moly steel. Chiappa obtained the mfg. And marketing rights. Their M6 over under + inserts retail for $750.00. So the insert set for $221.00 is a 10 caliber single shot bargain.
