The Brass was recent production Super brand. I have Military Ruptured Case extractors in .303, 7.62 Nato and .30-06 which would possibly grip the neck, but due to the length of the extractors and the fact they are designed to work with bolt/sliding block actions they are not suitable for the .310 Cadet. What do people suggest to extract the neck from the chamber? Also, on some fired cases in this rifle, there are concentric machining ridges in the chamber that have left impressions in the cases that would have contributed to this neck separation. What can I do to polish out these ridges without enlarging the chamber too much?

Plug the bore with a wad of cleaning patch about 1/2" forward of the chamber, and pour a Cerrosafe chamber cast. Let it solidify and use a brass-tipped steel cleaning rod to push it out of the chamber. You can melt the Cerrosafe off of the brass and save it for the next time you want to make a cast...or have a similar problem. Brownells, Midway and Buffalo Arms sell Cerrosafe.

He tried all the above mentioned methods without success, before asking me for help. In the end, I had to wind the barrel out and use an undersized reamer, fed by the lathe tailstock but turning the chucked up barrel by hand. Periodically, I released the tailstock from the bed and pulled on it. With about 1/8" of case left, it pulled out. I guess it had probably been there for a long, long time. There was no chamber damage and no corrosion. The rifle is back together and shooting well. Fred.

A 44 or 45 pistol brush should work. Put the cleaning rod down the muzzle , screw the brush on and pull the brush back in the case neck so the brush is fully in the brass. The new stiff bristles of the brush will bend back. When the brush is fully in the brass, then give the rod handl a sharp rap with your hand. The bristles will dig into the brass and it should come out. If it doesn't, then proceed to Dave's trick. Never ever squirt oil in the chamber to help it slide. It won't. The oil will the air out and adhere the brass to the wall. When customer brought guns in they sprayed oil in I would have to use gun scrubber or carburator cleaner to get the oil out. I have had the case dropout from contraction effect of the cold spray. Douglas ******* To find things Martini go to:Martini Internet Resource List**

I wonder if spray ether might even be colder? I think I would spray the carb cleaner up there in case anyone had previously oiled it, prep the rod and new brass brush to be ready to go, hit it with the ether and do the rod/brush technique quickly.

It's been quite a few years since this product was offered...probably the environazis won't let it on the market anymore. David Kaiser Montezuma, IA

(cartoon time anyone?) I do admit to having not checked the proper nozzle orientation on occasion, but should have mentioned that as an alternative to the other hornet spray chemicals I prefer a QUICK spritz of the ether indoors. Wake me up now.........

Being naturally after the quick fix, I tried the quickest least messy method first, and it worked! Our local supermarket sells tinned Ether sprays for treatment of warts (Eeww!). It works by spraying an amount of liquid ether on to a foam applicator, waiting a few seconds until the liquid evaporates, which then drops the wet applicator tip to freezing. I won't detail how you use this on the wart, but the applicator is a perfect size and length to reach the appropriate spot in the chamber. I left the rifle in the sun for about an hour to warm the metal, but still able to be easily handled. I guess you could heat it with a small propane torch to accentuate the effect, but you'd need to remove the woodwork first (Read the second line of this post). Using the applicator as described, it was inserted into the chamber for about 20 sec to evaporate and freeze. I then removed the applicator and gave the rifle butt a rap on my shoe, and the neck of the case simply fell out!

Lets see......if you repackage and sell to the firearms crowd you should be able to quadruple the price. "Dr. Scholl's Stuck Case Remover" just doesnt have quite the right ring. Well done.
