	Somewhere in my vast collection of gun related literature I have read about reaming a Martini Cadet barrel to smooth bore. If I recall correctly it is only a couple of paragraphs. It tells what reamer to use that will produce a choke (probably a hand reamer). It even explains how to make a ventilated rib from 3/16 square stock. It sounds like it is something de Hass would have written about but I can't find it. I have a Cadet barrel that is an excellent candidate for this conversion and I feel it would make an excellent Carpenter Bee gun. Loaded with grits it should be a blast--pun intended. It would also help get rid of these **** destructive little pests. If anyone knows of these instructions I would be grateful to be pointed to them. Bill PS I ain't jokin'

Bill PS I ain't jokin' No idea about the article, but an adjustable reamer would do the job. You don't say what bore you want, but an adjustable reamer would do the barrel and the choke. You would need a special reamer for the breech, and getting the headspacing right is a 'must'. IIRC, the barrel/receiver thread is 1" x 14 tpi, but I can't remember the pitch. -- Aonghas

	Yes. Very familiar with Cadets. I have a stable of them. I really love those little rifles. It's been a long time since I read about reaming the barrel but I seem to remember that the reamer made the bore suitable for a .357 sized cartridge. And I don't recall anything about boring before reaming. I need to read that article again. Bill

	Have often thought of playing with exactly such a project, the Cadet action would work well but so would any of the smaller actions, perhaps ( would have to check out the pressures ) even the lowly 44 might do especially if kept to Pyrodex or black. It would all be a playing with the numbers game to make everything work out but thought of blowing out the 30-30 case kind of like a .375 Winchester and winding up with a .375 dia. bore size. Reamers would be no problem as you could base the bore off of standard .375 ( 3/8") reamer but you would have a bit of special grinding involved for the forcing cone and choke. One would either have to make a half reamer or have a chambering reamer ground up but you could use standard 30-30 head space gages to control headspace. Wads could be cut by hand with a punch as there would be no "factory " wads but am wondering if shot wrappers could not be made by cutting milk jugs into strips and then cutting to proper length. Loaded with a moderate load of rice grits or even wheat it might just be the ticket for those carpenter bees or even for any form of saber tooth crotch cricket on the loose. Actually though, am thinking with #9 shot it might be a real bunny getter up to 25 or 30 yards or so. One thing is for sure, you would be the only kid on the block with a shooter like that !!!!

	Ok! Everyone can stand down. I found the article. It is by de Hass and is in a book titled" The NRA Gunsmithing Guide- Updated". The .310 bore is simply reamed with a No. 6 taper reamer which is supposed to lead itself through the bore. The operation is stopped as soon as all the rifling is gone at the muzzle leaving a choke. I ordered the reamer yesterday. I have a Cadet chambered in .357 Magnum. Maybe a Maximum case without a bullet will chamber. Bill

	Bill, Maybe you have already figured this out, but don't think a #6 taper reamer (.354" max diameter) is going to clean out a .357 bore. A #7 is too large unless reground. Chuck My bad. Re-read your first post and you are using another .310 bore which should work. The .357 confused me, which is not hard to do.
