While I'm waiting on my 44Mag double to be built I spent a few $$ for 38 special inserts for my 410 double. Finally got a break (raining) to test fire it. Using the shotgun sights and some cowboy action reloads I set the target at 40yds. Looking straight down the barrel I put the bull on top of the front bead. Pulled the trigger and the impact was center of the bull but 6" right. Left barrel hit exactly 1.5" left of the right. Four more pair and I had a 2.5" hole.

Anyone have any experience with inserts? wondering if playing with swapping and or rotating might move the impact. Don't want to add sights or alter the shotgun. It has been in the wife's family since at least her grandfather.

I bought a 38/357 insert for my Savage 24V, have not gotten to a range yet to test. I'm hopeful, it's a rifled insert.

My inserts are 6 or 7" and rifled.

The wall thickness must be mighty thin.

I made a 30/30 insert for a 12 gauge SxS Stoeger. It is the full length of shotgun barrel, 20”.
Made for turkey in Texas where a hog might show up. I don’t care for slugs.

I'm thinking about mono blocking a pair of barrels into a 410 double shotgun with a pair of 20 inch barrels chambered for the 256 Win Mag, and regulate it to factory ammo, for varmint hunting. Then giving it to my great grandson when he is old enough to go with me, and his dad to hunt coyotes, and bob cats.

Bore is .355 same as they use for the 380 and 357mag. The 410 insert is listed for std 38sp pressure or lower. It appears they no longer make the insert for the 2.5" chamber like mine.

Mac that would be a fun combo. I have a 28ga SXS at Aaron Littles. It will be a simple 44mag double when it gets back. Fun to shoot cheap to reload and big enough for deer and hogs.

Thin? How thick do you need for a 38 special? They have practically no pressure which can be held with a piece of electrical conduit. If you have ever seen an RG revolver you will know how thin it can be.

I was thinking the barrel would be into the .410” diameter of the bore. Just being length of chamber it’s much thicker.

I see no reason to use a bore liner when full length barrels can simply be mono-blocked into the first three or four inches of the reamed 410 chamber end of the shotgun barrels, and be regulated for the pistol cartridge.

Why not just build a real DR on your 410 frame? Maybe you want to convert it back to a shotgun someday. It is not quite that simple a job.

That's what Ellis Brown did for my son's 410 about 8-9 years ago. Here is is prior to rust bluing. 24" shoe lump 25-20 barrels with a 2x leupold.

mine started out as a Wm.Parkhurst 44XL.... the predecessor to a .410... basically a .44 caliber shot cartridge 1 7/16" long, but .432 at the muzzle... I bought it on GB as a .410, but couldnt' get the 2 1/2" shells to chamber.. sent it to a gunsmith, while I was waiting on a report from him, a friend at the Ft. Worth gunshow told me what I had... so we reamed the chamber to 2", and shot RST 3/8 oz shotshells in it.. ahd a .38 chamber made and shot those too... sadly the gun was stolen along with 114 others in January this year... it was a neat little 5 lb hammer Damascus double.... before you jump me for shooting Damascus, I used the low pressure stuff RST especially makes, and the barrels and action were checked by several reputable gunsmiths...

Who made the inserts for the 410?

O Bob
Nice rifle.
Ellis does good work and teaches gunsmiths how also.

Where does it pattern as a shotgun? You may find the front bead is off anyway. 6" at 40 is .1" on a 26" barrel.

You have won 2/3 of the battle already .. getting both barrels shooting in the same place.

Great point

Thanks

Never got around to testing the pattern. But did epoxy on a rear sight so it allows me to bracket the front bead pretty much like a pistol sight. Now the bullet hit the bull. Sure fun to plink with.
