I ordered some shotgun sub caiber tubes in 45-70 govt. This outfit makes alot of inserts allowing one to switch calibers fast. might be good to have a few if you only have 1 firearm and need a smaller caliber. Or if you want to shoot 357 mag out of your old 20 gauge. The long tubes are a gunbarrel that fits inyour barrel. They can withstand the pressures of chambering not inserted in the gun! safety is not a issue. see shotgun tubes at
mcace.com/shotguninserts.htm dont forget to add the www. before it
I think this may intrest you guys

An interesting and unusual purchase, to say the least.

I have been reading numerous gun magazines for three years and have never come across anything like this before. I think it could well save you money as well.

they also sell inserts to allow a .30-.30 to fire a .32 acp shell. You can take out the odd rabbit with very little meat destruction and a lot less noise.

from what i understand, the point of impact of the shotgun adapters will change if it is rotated in the shotgun chamber. find the position that puts the bullets as close to where your sights point as possible, then mark the adapter lightly with a file or something at the 12 o' clock position

these make it impossible for police to perform forensics on a gun, should they recover one from a crime scene. Unless your sloppy enough to let them find the converter tube.

You could allways just buy a dozen really cheap conversion kits. After use you just smack it a few times with a sledge hammer and toss it wherever you please seeing as it can not be easily tied to the crime.

some questions that popped into my head while reading over the site.

are the inserts cast molded? or lathed?
what type of steel is used?
are the inserts rifled?

maybe i'll give them a call later.

Its from experience. I do a lot of metalwork and know that it would be impossible to make a barrel in any other way than rolling, drilling on hammering. I shouldn't say impossible. Just extremely unlikely and uneconomical. I am sure that these are lathed. For the material its a bit obvious. Either it stated its life as mild or stainless steel and got treated to be very hard by either multiple stages of tempering or a carbon bath.

Out of curiosity do these still need you to use a wooden dowel to eject the spent casings ? I had a few years ago but have long since lost them.

i haven't seen anything on the sites about modified ejection assemblies so i think you would need a dowel or the like to eject the spent cartridge
