Try Cerrosafe Alloy melting Temp. 158-190 F this is the Temp. of hot water. This alloy will expand to give a perfect tight chamber reading. It can also be used for checking bullet molds etc. The problem with most home made chamber cast wax or various school supplies they do not expand when cooling. This is most important for a correct chamber reading.
My guess is that you have a 25-20 Stevens. This rifle is not the same as the 25-20 WCF. The 25-20 Stevens and Cerrosafe can be ordered thru firms listed in the post.
