they make adapters to fit in the barrel of a break action shotgun that allows you to fire pistol and rifle cartridges through your gun. has anyone tried these before?
it seems to me that a cartridge like a 30-30 would produce too much pressure for a shotgun action. what do you think?
if it doesn't seem too dangerous i might order one.
well i can't imagine it but seein as they sell them at large retailers and what not im sure they have tested them extensively and they must have passed. i doubt they woudl want the liability of a gun blowin up on em. but im still not tryin one.
I don't think the insert rely on the shotgun chamber to hold the pressure. I think they're more of a chamber in and of themselves that are fitted to the size of a shotgun chamber and bore. If they didn't cost that much I'd try one.
They made/make? them and they are safe if the receiver is strong enough as the high pressure of a,say .30-30 (about 35k cup) is dissapated as soon as it is released in the much larger shotgun barrel.Unfortunately a shotgun receiver is designed to handle about 20k CUP and lower (usually about 12k cup) so the extra 15k cup may very well crack the receiver where the part for the barrel and the part for the trigger/hammer join.This is also why NEF,H&R will not sell you a centerfire barrel for a shotgun receiver. ,,,sam.
I know they used to make insert barrels for the Savage M24. I do not remember who made them. I met a guy at a range back then that was shooting a 223 insert in his 20ga barrel.
UPDATE: I found this company online. He's right here in Anchorage !! I called the number and got a standard recording. Will call again later to see if he is still in business.

Since a .223 is loaded to about 50,000-52,000 CUP, that sounds dangerous. Sam's right, the pressure of the rifle cartridge will more than likely have adverse affects on the receiver.

OK. Still no answer. But I do have a question ?? Why is there no adverse action when shooting a 223 on a Savage M24 ??
The best answer to your question is even tho the gasses are released and drop to a safe level,being released inside a shotgun barrel they are confined to close procsemity of the bullet.Even in a crowned rifle muzzle when the bullet and gasses are released the gasses cause extreme trauma but only for a milisecond as they can spread wide quickley.This trauma does effect the stability of the bullet but it is stabilised again by atmosphere pushing equeally on every point of the bullets body,Counterboring worn crowns bring back some accuracy but increase the trauma effect because they hold the swirling gasses in close proximity of the bullet longer than if the bullet/gasses broke clean from a full length muzzle.Consequently it takes longer and more effort for atmosphere to straighten the bullet in flight.(usually the bullet doesn't stabilise completely) If the bullet is released in a shotgun barrel and has several inches of confined gasses to beat it around and make it unstable that is much more than the 2",s or so of a counterbore so it takes longer in flight for atmospheric pressures to stabilise it.Add the natural imballance to all bullets and they may never stabilise.It amounts to quick release vs confined quick release.And gasses being lighter and under pressure outrun the bullet meaning the bullet is getting buffeted in the shotgun barrel from all swirling angles. ,,,sam.
I get what you are saying Sam. But I am talking about an insert that is the same length as the shotgun barrel. I really wish I could remember the company that made them.
