I am very excited about this project. I built a .218 Bee Cadet rifle after school with the help of the Auto Shop teacher in 1961. I sold it in 1965 and have wished I had it ever since. Right now I am planning on making it into 5.6X50R mag.

My Cadet rifle arrived today and I was very pleased with the condition of the metal, wood and especially the bore. The action is smooth and tight and the
trigger is crisp. The rifle has been re chambered to .32 Winchester Special and I will pick up a box of ammo to shoot before I tear the thing apart and make a
varmint rifle from it. I will try to figure out how to post pictures and hopefully tomorrow.......... This rifle is missing the butt plate but Numerich Arms
seems to have them so I will call them tomorrow.

I think you would be better off sticking to a 22 hornet 218 bee class varmint rifle. Cadets are strong actions, but the chamber walls get awfully thin when you
chamber them for a shell with a larger diameter than a 218 bee.

Joel,
5.6x50R mag is more or less like a long, rimmed .222 mag, base diameter is pretty small - it shouldn't be a problem. |

Here are the rim and case at the rim diminsions for cartridges as noted:
.310 Greener .410 Rim .349 Case @ Rim .32 Win Spc .560 Rim .422 Case @ Rim .22 Hornet .350 Rim .298 Case @ Rim .218 Bee .408 Rim .349 Case @ Rim 5.6X50R mag .429 Rim .377 Case @ Rim I have it from someone I turst and other authorities that although the .225 Winchester has been used successfully in the Cadet action, the rim is very narrow and ejection is sometimes a problem. .225 Win .473 Rim .423 Case @ Rim The only problem I forsee with the conversion I plan is that the extractor/ejector has been opened up to accomodiate the .32 Win Spec and the 5.6X50R is considerably smaller but with a little machine work. |

I guess gunsmiths are braver than I was in the 1960's when I did that kind of work.

That's true, the .225 Winchester has been successfully used in the Cadet. It also has an extensive histroy of bulging walls in the .225 Winchester chamber
and sticking cases. The reputation is well known.
Do the Math. .750 diameter barrel tenon minus .423 chamber diameter equals .327 divided 2 equals .164 wall diameter minus .0526 thread depth equals .111 chamber wall thickness to hold a 46,000 cup to 52, 000 cup cartridge, or 46,000 to 57,000 psi. This is pushing the limits both for the barrel tenon and a 100 year old rifle action. I have done a couple of these a long time ago. I can recall two, relying on 61 year old mind remembering events of 20-25 years ago. I remember these two because they were both brought back for sticking cases and the case bulges all appeared as transmssion of the barrel threads. I am trying to be very careful to not cast apsersions here as I was an idiot for doing it myself years ago...never again, I am smarter that that now. The extractor weld up and refitting is so simple it shouldn't even be part of the equation |

Thank you DD, I believe it was you and a gunsmith you recommended (Vic Samuel) that cautioned me against even considering the .225 Winchester. It was
Martinibelgian that mentioned the 5.6X50R as being as big as I might practically want to go. All of what I have been able to find out about the 5.6X50R seems
to be in line with what I want and what people that know more than me feel is about the maximum for the action.
Doing the math as per your example I come up with a chamber wall thickness for the 5.6X50R of .1339". With about the same taper as the .225 Winchester but smaller dia., shorter sholder area and longer case neck the round, with the help of hopefully better steel now than then, ought to work. Does anyone have any recommendations as to the twist rate that would be best for 50, 55 and 60-62 gr bullets? |

I have never done a 5.6 x 50R in a Cadet. Always intended to. The 5.6 x 50 R is a pretty intense round and you should not exceed published data.

My soon to be 68 year old brain remembers a cadet coming into my store with a bulged chamber. It had been fitted with a barrel chambered for the rimmed .222
case. Back then cases were available from Australia. It certainly could have been caused by an overload or it might have been a low pressure barrel (although
this is unlikely because it was .224 with a 1:14 twist). At the time we wrote it off to thin chamber walls. I'm sure better steels are used in current
barrels, so all this may be moot.

Joe, are there any current barrels that you would recommend? What twist rate would you recommend for 50, 55 and 60-62 gr bullets with velocities between
3,100fps and 3,500 fps? It is my understanding that S&B loads the factory 5.6X50R to 3,445 fps with a small amount of very hot powder and that with larger
amounts of different powder the same results and even greater velocities can be achieved. I am still learning and any and all advice is appreciated and
considered.

I am the last person you should ask. I'm so behind the times that I would still use a 1:14 twist for a .22 for those bullet weights. Here in southern
Wisconsin we are spoiled. We have both Krieger and Badger making wonderful barrels and there are still great national standbys like Douglas.

Hello; About five years ago, I imported a cadet that had been restocked, and rebarrelled to 5.6X50R Mag. I think I gor my dies from Double D, and a bunch of
RWS ammo from Jim Wasmundt. I querried Accurate Arms regarding loads, and was told that .222MAG data would work well.
Seems to. I loaded up a batch using 40 grain Nosler Ballistic Tip bullets and 2520 powder to give about 3100fps. Notes in my book indicate 11/2" at 100 yards. Not great, but we were plinking, not really trying too hard. Had a Leupold 3x9 scope on it then. It now has a Fecker 7X Woodchucker scope. I haven't shot it in that configuration as yet. What will you do with the 32 Special barrel. If its for sale, I'd be interested. Ed |

I just bought a box of .32 Win Spec shells today at the local gun store....I just about passed out from sticker shock...$35 plus tax! Wow, with tax about $2 every time you pull the trigger! But although I could have purchased cheaper on line, I wanted instant gratification and plan on shooting tomorrow. |

I'll watch for your postings. Some folks say that the recoil of a 32 special cadet is pretty harsh. I don't know.. 30-30 is as heavy as I've
fired in a cadet, and its not bad. Please get back to us on the recoil, will you?

I second Ed opinion, try it before making canges..
You can try .32 Special and if it have too much recoil, you can recreate the .30-30 "Short Range" load, also known as .30-6-110 (.32-7-110 in your case,LOL). JMHO Martin |

Just bought a box of 32 Win Spec cartridges. Wow, they must be gold plated! I could have done better on the net but I wanted instant gratification for shooting
this week. At almost $2 every time I pull the tirgger, I don't see much future for the 32 Win Spec as far as I am concerned.

Went to the range today and shot the Cadet. 32 Win Spec is easy to load and has moderate recoil. Managed a nice 1" group at 50 yards about 8" high
with the sights set for 100 yards. All of the 100 yard positions were filled so I kept it to 50 yards. Fun to shoot and it functioned flawlessly. Looking at
the fired cases and the firing pin indentions, it doesn't look to me that the firing pin has been turned and bushed.
Several people at the range offered comments and questions about what it was and could a scope be mounted. I guess no one shoots iron sights any more. |

Are you shooting 180 grain or 150 grain bullets.

Neither, I am shooting Remington 170 grain Core-Lokt SP the only thing I could find in the area.

RON E.
Can you show a picture or two of a 32 Special loading into the Cadet? I want to make mine 32 Special or something. I live in Austin. Do you want to sell your barrel? Bronco B. |
