Will a 30-30 or 7-30 Waters (7mmx30-30 round) work in a cadet action? I am wondering whether they will "make the bend" into the chamber.

The 30-30 might make it, but you might have an issue with OAL - you will probably be limited to short, deep-seated bullets. 7-30 Waters would be easier, and a better option IMO. Probably the ideal hunting round for this little action. Just make sure you put some weight on the rifle, or recoil might become nasty...

Doubt it. Action is too short and too small. Cannot safely convert to .44mag.

There are, However a few intermediate martini actions arround. They were typically chambered for the .450 No1 carbine round (ie .450 x 1½"). Here in Zim they are sought after for converson to .44 mag or .454

Klien's, in Chicago,sold Australian Cadets chambered for the .32 Winchester Spl. in the 1960s.

I handled one in the 1970s in a gun shop,I don't recall that any alterations had been made,except the rechamber, to allow it to chamber the .32 Win.Spl.

don't think you'll make the bend. I've got one in 222 (snapps extractor) that just makes it. I believe the thicker case wouldn't go

I had one in .32 Win. Spl. Loaded just fine, simple rechamber job. Accuracy was not very good, probaby due to improper bore size. Should have just used a cas t bullet, but when there was an article in an American Rifleman where they considered the conversion unsafe due to too thin barrel walls at the chamber, I got rid of it. Kind of sorry I did that in a way, but that was many years ago. I do kind of agree that the barrel walls were probably too thin, but then, I never heard of one letting go.

Why convert to .30/30? The .310 Cadet is a great little round and can be loaded a bit hotter if you want also ammo is available again. I have seen Cadets in .357Mag,.22Hornet,.222Rimmed,and .30/30 and .22 Savage Hi-Power! but I think the pressures might be a bit high in the last two.

I am thinking of the 7-30 Waters because I was given a barrel with integral 1/4 rib, ramp and swivel that was supposed to be for a 7mm mag. The barrel turned out to be stainless instead of chrome-moly, and because of the light contour, the manufacturer recommended against using it for a high pressure round, so the barrel is scrap unless I cut off the shank and put it into a smallish action.

You should consult Robert Snapp on this question. He is widely regarded as the leading authority on customizing the Cadet. I spoke with him at the Guild show in Reno this winter and he had very high praise for the 7-30 Waters in the Cadet action. As I recall, the round can be loaded too hot for that action, but if you stay within prescribed pressure limits, the Cadet will handle the 7-30 Waters with aplomb.

P.S. You can reach Snapp at [989] 386-9226. He is in Claire, Michigan.

Jordan:

Thanks for the information, as I love the Cadet, and have a line on a rimfire action that has had the firing pin bushed for centerfire, and the action face trued to the bore.

Jordan:

I just talked to Bob Snapp. It looks like I have a Martini cadet in 7-30 Waters in my future.

Dave

I guess this too late to help you any, but personally I would get either the .32 Miller Short or the .30 Herret chambering over the 7x30 Waters. If I wanted REAL accuracy, and wanted to use lead bullets much of the time, I'd get the .32 Miller Short and a Paul Jones mould. And with that little action, I'd keep the loads down for WHATEVER I got.

Outstanding----but don't send him yours till I get mine back! [.20 Jet Improved] Actually, I think Bob is quite prompt and well organized so I am sure you will have yours in short order. He makes a heck of a compelling argument for the 7-30 Waters on a Cadet action as a walking deer rifle, doesn't he?


Jordan

By memory I believe I've shot one in 219 Zipper
(224 on a 30-30 case.) I suppose the bigger hole at the chamber over a 222Rimmed would give more clearance.

I have Bob Snapp making me a 32-40 Cadet right now with his own design septagon barrel. I also found and purchased a .357 mag cadet in original configuration he had rebarreled and bushed the firing pin for another customer. It shoots very well. He does great work.

His personal 7-30 Waters is left handed and a very fine piece of work. Of course I'm also a lefty so it's pretty special to see such a special piece made for us leftys.

Jordan:

Actually, since Duane Wiebe gave me the barrel, I am having him install it and do the work, so I shouldn't slow Bob down.

ChopperGuy:

Did you get the .357 that was on one of the auction sites a few months ago? If so, it looked like you got a great deal.

Dave

Yes, that's the rifle. A bit more than other converted Cadets go for, however I knew of Bob's work and what the conversion (new barrel, bushing, etc) would have cost so I still have less invested.

Even the 310 Cadet barrel take-off with sights for sale if any one needs a nice barrel.
