Potential .327 single shot rifle solution: Chaszel .410 to .327 adaptor.

[Oninotaki]

Well folks it looks like I might have found my cheapest and least complicated solution to being able to shoot my .327s out of a long arm platform. Introducing the Chaszel .410 to .327 adaptor in 16".

I just came across these today, and bought one immediately. Once it arrives I will test it out in my Chiappa Double badger in .410/.22 wmr, and my Rossi Tuffy .410.

I am hoping it works nicely out of the double badger as that already has very nice and accurate sights.

Depending on how well it works I am also really tempted to find a nice .410 O/U or SxS and try to pair the two together. That sounds like crazy good fun to me.

Oh man or maybe even get two .327 adaptors if it works really well and have a double barrel .327! Hell why stop there I could drop $1800 on a Charles Daly Triple Threat .410 and have a triple barrel .327

The TPS M6 160 is an O/U .410/.410 with built in front and rear sights, takes down nicely and has storage space in the stock for shells. That might be a fun platform to convert into .327/.410.....

If you guys can't tell, I am a bit stoked to find a full size .410 to .327 barrel adaptor for such a reasonable price. I hope it works worth a damn. No matter what I will let you guys know how it turns out.

I bought a 12 ga H&R once that had a 38 special chaszel adapter in it. It worked good but I didn’t really have a way to aim it as it didn’t shoot to where my eye lined up with the bead. I’ve thought about getting two of the 16” 410 to 38 special adapters and just permanently epoxying them into a 410 OU and putting rifle sights on it. I wonder if you could regulate the POI of the two barrels by clocking the two inserts.

 

[Ugly Sauce]

That is the problem with them, they may not shoot to where the sights are looking. Or the bead.

 

[Roverguy]

Voila: rook rifle. Cool.

Possibly, but why not one .38 barrel and one 410? Combination gun. For a close up follow up shot put a Brenekke slug in the 410 barrel. Just regulate the sights for the .38 adapter barrel. ?

I have a feeling I am going to get a lot of use out of my bore laser with this project, and will become a pro at using JB weld to add sights

 

[Ohen Cepel]

Nice find! Please keep us posted on how it goes.

I would test a variety of ammo before making/moving the sights. May find a happy medium along the way.

Because then it would be a combination gun, not a double rifle. I want a mini double rifle.

Solder works pretty good and you can adjust if needed by just heating it up.

I have a number of chaszel adapters for my 16 Ga. Accuracy is terrible and they are very fragile due to the thin steel.
Waste of $$$ except for dire emergency usage, IMO.

Hope you have better luck than I did.

Okay, I got it. I've always thought a combination gun was more useful than a double rifle, so I just had to mention that.

I don’t disagree but I would probably just buy a combination gun if that’s what I was going for. That would certainly be the easy button solution.

 

[Ugly Sauce]

Yes. True. My "dream gun" is a double barrel 20 gauge, with the left barrel sleeved to .45-70. Someday. Maybe.

I've always wanted an over under with a 12 ga choked barrel on the top, and a rifled 20 gauge barrel on the bottom, but with the same outer wall thickness. Kind of like the old H&R ultra slug guns where they would use a 12 gauge blank to make a 20 gauge thick walled rifled barrel, or a 10 gauge blank with a 12 gauge bore. I wonder how much a guy would have to spend to get such a thing built.

This would work well if you have a shotgun that is drilled and tapped for a scope rail (or you could have it drilled). Otherwise aiming for this with a shotgun bead is going to be pretty inaccurate.

 

[Dave DeLaurant]

If you have a centerfire rifle in .303 British, 7.92x54R, 7.7 Japanese, etc., the bore diameter will work with a simple chamber adapter. I prefer .32 H&R rather than .327 Federal, but that's me.

If you load soft lead HBWC bullets and keep the velocity modest, you can even use one of these in an oversized 8mm bore.

That is not a problem, for sure one would want more than a bead. I prefer rifle sights over a scope, but either one is doable. I have a couple of shotguns with rifle sights, just for shooting round-ball or slug loads. You can even use a flip-up/flip-down rear sight if one prefers to just use the front sight as a bead for shot loads.

I have a combo-gun in .30WCF over 20 gauge, the rifle sights are set for the rifle barrel, then flipping the rear sight down gives me faster sighting for shot loads, and also a sight picture (a bit crude but adequate) for slug loads in the 20 gauge barrel.

 

[Ugly Sauce]

I don't think it would be too bad. Not cheap, but not crazy rich-man expensive either. In your case, starting with a double 12, and sleeving the under barrel to 20, I don't see a super-expense. The ejectors or extractors would require some expertise, but sleeving and rechambering is not a big deal. I don't think full length sleeves are that expensive either.

Small update for those who are curious. I have received the adaptor but not yet had a chance to shoot anything through it as the weather has been too cold here.

It slides into my Rossi Tuffy 18" Barrel single shot just fine, but sadly is two large to fit into my Chiappa Double Badger .22wmr/.410.

This does mean that I am keeping an eye out for a standard .410 O/U or SxS at a decent price. I am thinking a Stoeger in either configuration is going to be the way I go, but am not certain.

Anyone got any advice as to which of those would work better used primarily as a .327/.410 combination gun?

 

[Ugly Sauce]

I have 20gauge to .410 adapters, and 12 gauge to .410 adapters. The 12 gauge adapters (Little Skeeters) would not fit into a couple of my older 12 guage shotguns. I was able to shorten them a little, and then they fit and worked fine.

When you say "too large" do you mean in diameter or length?

In diameter of the barrel after the chamber. Because the Chiappa Double Badger has a 3" shell chamber the adaptor smoothly enters the barrel up to that depth, then stops when moving into the barrel proper.

 

[Ugly Sauce]

Okay, so the diameter of the adapter's barrel is greater then the bore of the Badger's barrel. ? How long is the adapter?

That is correct. The OD diamter of the adaptor is greater than the ID diameter of the Badger's barrel. The adapter is 16" long rifled adapter so that's where the problem comes in.

Okay, that explains it. Badger has a tight bore. Yeah that's a bummer, would have to turn it on a lathe to fix that.

I love the idea of a chamber adapter that lets my shotgun also shoot smaller gauges, centerfire cartridges, etc. One gun to do everything. Cool.

The problem is that realistically a shotgun works in a dispersion pattern so it really doesn’t matter too much if there’s a little slop in your system somewhere. Shooting a .410 shotshell out of a 12g with an adapter will be workable.

Shooting a 9mm, 32 mag etc in a shotgun….whole other question, because that adapter usually slips in to the chamber and barrel of a shotgun and has a self-contained rifled barrel, like a gun within a gun. It’s not an interference fit so unless you epoxy that sucker in, it’s going to wobble around minutely, which is going to play hell with your accuracy. A chamber adapter for a rifle isn’t going to be a problem in that way because the bullet will still be aligned by the rifling. Maybe not as perfect as the actual chambering of the rifle, but pretty good.
