FWIW - ctg conversion for Cadet (Read 1400 times)

	I picked up a Cadet within this last year that was chambered for "30 Carbine Rimmed" which was made from 32 Self-Loading (read: unobtainium). By chance, the 327 Federal Mag casing is VERY close, being a whisker (1/16-1/8") shorter. Off to the range soon....

	This being a Martini Cadet, I'm assuming. John

	What about taking 32-20 brass and running it through a .30 carbine die? might that work? If the chamber is tight enough perhaps have it rechambered to 32-20 as a solution. Sam

	If it's the original barrel, you'll still need a heel bullet, groove dia. is about .320. Good news is they do shoot quite well.

This is the correct mould for the .310 Cadet bullet. (You need to *Login* or *Register* to view media files and links)

FWIW, it might be or be similar to the .30 Johnson Special. It's in Donnelly's manual. Have you made a chamber cast? Good luck!

	I'm starting with some store-bought .312 dia 'cowboy' bullets 120gr. Popped a primer on one and it went an inch or so into the bbl. Tapping it out the engraving looked good. (not sure how much was from the tapping it back out.) The .327 H&R and .327 Federals match the diameters of the rounds (30 carbine rimmed made from 32 Self-loading). Loaded bullets today, range later this week....

	You should rid yourself of the cadet quick! The damn things will take over your safe.

	If the chamber will take them, another solution is to run an 8mm expander into .32-20 cases essentially making a straight case, and use light 8mm bullets. I had a Cadet that a previous owner had opened up for this (marked on the barrel as 8mm NAG). It shot quite well with 125-grain jacketed 8mm bullets. I used an 8mm Mauser sizing die I already had to expand the case necks, and then after seating bullets with a .32-20 seating die, ran the rounds part way into a .32-30 sizing die which crimped the bullets.

	brass gets swelled a bit from firing. Hmmm. I'm thinking of having the barrel shortened and rechambered to 327 Federal.

If the chamber is tight enough perhaps have it rechambered to 32-20 as a solution. Sam I originally thought this not possible because of the closeness in diameters of rim and base of the 32SL and the 327FederalMag. BUT, seeing the swelled 327's, I took an 8mm x 1" (made from the 32-20) and it chambered and extracted. THEN I tried the 32-20 which stuck, and the 25-20 which chambered. OK. The rim on the 32-20 is too thick for the bolt to close - an easy thing to thin down on the lathe. SO taking the 30 Carbine sizing die on the 32-20 case (just the top 1/3) made a cartridge that chambers very well. Cold here. THis will take some time making up enough brass to play with; but the solution is near on the horizon....

When I tried a 32-20 it wouldn't chamber - because it was fired in another gun. A NEW 32-20 (and a resized 32-20) both chambered!! SO what I have is a 30-20 with a THINNER rim than on the 32-20 factory ctg. Snowing now - - it will be a while 'till I get to the range....

	32 WSL has a thinner rim than 32-20, and base diameter is only about .004-5” less at .348”. It’s easier to use 25-20 brass than 32-20 to make it. Sounds like it’s chambered as marked.
