I swear I saw on here just a day or so ago a link to a replacment barrel for your shotgun that turned it into a blunderbuss, supposedly for home defense, but I cannot remember where....

and search function was no help. I think the term blunder kept on getting found.

I know what you are talking about. Can't give you a link, but I saw it.

I went and looked for it, though- appears the website is now offline.

I've seen that too. Worthless. You'd get ridiculous amounts of gas blowing past the wad once the barrel opens up past about 0.800", which would most likely just screw up your patterns without actually widening them any. You'd also get a lot more noise, and less velocity.

OK, quick history lesson here.

The blunderbuss' bell muzzle was to permit easier muzzleloading of shot from a moving coach. It was in no way a superior system for spreading out the shot pattern.

RyanM is dead on. A blunderbuss barrel is worthless in a breachloading shotgun.

Although I agree that a modern blunderbuss would not produce the results many expect, I would like to see a link to its website. Curiousity has a hold on me.:D

short-barreled cylinder choke (coach gun) is as close as you will come legally. my coach gun SXS is improved cyl. left, modified right barrel. good bush bird gun and bedside gun.

A repro of an original could be fun!

Armoredman, as a muzzleloading enthusiast, I am sure replicas of flintlock and percussion cap blunderblusses are available. With a little research, we should be able to discover them. If you have a serious interest in these firearms, some of our members in the black powder subforum may be able to answer your questions.

I'm sure I've seen this before. Looks like their website is out of commission but you can still find it on The Wayback machine: http://web.archive.org/web/20070106051056/http://www.housegun.com/

There was a device used by the Army that attached to the muzzle and spread the shot charge horizontaly!

Duckbill attachment for shotguns... IIRC, there's a firm out there somewhere making replicas..I seem to remember hearing about it in SAR a year or two ago.

oneshooter, that's like the famous "diverter tube" on the SPAS-12, which could be rotated to spread shot either horizontally or vertically, IIRC.
Timthinker, I like blackpowder, but that's a project that would have to wait for more fundage. :)

I want the duckbill, I was very close to sending off an 870 barrel for it. An old issue of SAR deals with it. I want a replica bp blunderbuss for fun. The modern one was actually in an ad or something last year in an issue of Shotgun News or Gun List IIRC.

Reproduction flintlock blunderbusses are available from these places (among others). I've bought from MSVTC before, good folk.

I'll spend the money on practice ammo for the shotguns I've already got, thanks. :)

I think the one he's referring to is the "duckbill choke" they used in Viet Nam. Saw it in SAR.

I like the potato gun with a 3 inch bore.

I'd seriously like to see what would happen if you shot a 12 gauge blank after having jammed a tennis ball in the pipe :D

Assuming the whole thing didn't go kaboom, I'd think it would be a fun trainer for my Labrador retriever ;)

It would simply be pointless to have a flaring muzzle in a modern firearm like that. It shouldn't improve the spread much. Most shotguns use fast powders and tend to reach thier maximum velocity within 8 inches or so. So any flaring past that point would not have much effect on shot, and flaring before that point would reduce velocity.
It is generaly a myth that shorter shotguns have a significantly wider spread. No choke has a wider spread. Lack of barrel within the inches velocity is still being imparted can result in pressure pushing them sideways somewhat increasing spread, but then effectiveness of each projectile is degraded, and per projectile they already perform much worse than a bullet of the given diameter.
Rifling imparts an outward spin giving a wider spread (though in a donut pattern removing much of the pellet density from the center.)

So all around it would have very little effect on the projectiles. It would however make aiming more difficult, and it would increase the diameter of the barrel without really providing solid benefits. A lose/lose.

Really just one of those products marketed to people that want to give it a try. Not sold on valid logic, but if enough people give it a try, profit can be made in the short term, and then they can disappear and focus on something else, which it appears they did.
