Mystery single shot. (Read 2737 times)

	I have a friend who is trying to find some information on a custom single shot handgun he purchased at Rock Island Auctions many years ago. On the receiver it is marked "Wichita" and has wichita sights and on the barrel it is marked "50 cal" WHB BMF. The chamber is a bottle neck round with a long freebore to the rifling. The bolt is of the "drop in" style and is cut for a rimless round such as an acp round. Any information would be greatly appreciated. Thank you. JMH

	whb = Wichita heavy barrel bmf = big mother f must be a wildcat, maybe only one produced. Does it look like the chamber is cut for a belted magnum? maybe a 458 win mag to 50 cal?

	They also made front mechanical benchrest rests as well as their own single shot pistols back around the 70's. The first front rest that I owned for competitive shooting was one that they made.

	Wichita built actions and rifles primarily for short range benchrest, and varmint shooting. They built one action that used a bolt that accepted a shell holder to capture the cartridge. They were somewhat popular for a time in the 70s. I am not sure what you describe as a drop in bolt is, possibly the shell holder action? Some competitive rifles were built on his actions for the above, and also for silhouette shooting.

	You remove the bolt and "drop in" the round much as a shell holder would work. I forgot but the action has three locking lugs. JMH

	Rebel... The chamber is straight wall till it goes into the bottleneck. The whole thing kind of reminds me of the Beowolf round. A big fat cartridge with a rimless base... JMH

	Sad to hear. Met him at Tulsa back in the eighties, in fact bought a Schultz and Larsen single shot bolt action receiver from him there. Nice fellow to chat with.

	As said, a shellholder action, the lower cost version of their IHMSA silouhette pistol. I believe this was their proprietary chambering.....like a 30 Whisper only 50.

	Found out the gun was built by "Radke Custom Guns" but can't find anything on him. Ring a bell to anyone? JMH

	That's an interesting one. To state the obvious you need to slug the bore and cast the chamber to get a real idea of what it could be. The bottle neck throws me off. Good luck, ratseye

	I never have good results when I try that. My stuff always seems to get stuck. I use the Cerrosafe material. Any tips on making a good cast that won't get stuck? JMH

	I buy chamber casting alloy from Rotometals in San Leandro, Ca. It is much less expensive and has always worked well for me. A very light coating of oil or graphite in the chamber seems to help. I have done many bolt gun chambers that are more difficult than single shot actions as the chamber is not as accessible as a single shot chamber. Over filling is usually the culprit, and the casting material flows where it is not wanted. Pour very slowly. When you plug the bore prior to pouring, push the patch close to the throat so that you don't engage more of the rifling than necessary, as that can make removing the casting more difficult also. The folks, at Rotometals have been very helpful so a call to them may provide more answers or suggestions.

	JMH, In addition to a light coat of oil in the chamber and checking that the material doesn't flow into areas, that would lock the casting in place, I've found that you will do better knocking the casting out, as soon as it hardens. If you wait too long and it gets stuck, you may need to heat the barrel, just hot enough to have the casting flow out and try again. Otto

	Chipmaker is right, in fact on their (Rotometal) website there is a chart that shows the contraction/expansion factor. One does have to wait till the alloy has solidified before pounding away. Search for chamber casting alloy.
