About three years ago I purchased a combination gun marked "Heinrich Scherping" at an auction. The combination is a 16 gauge shotgun on top of a rifle which "I think" is 8 x 57 JRS. The reason why I say I think is because when I first purchased the gun I purchased, and was able to successfully use, two boxes of RWS 8 x 57 JRS ammunition. I subsequently purchased two other boxes from the same manufacturer and they don't fit (i.e. the gun wont close). I have been successfully reloading the first two boxes of cartridges and they work fine in the gun.
I am aware of the distinction between the 8 x 57 JR and the 8 x 57 JRS caliber (.318 vs. .323). Before I shot the gun I checked with the local gun smith who advised that it was a JRS caliber.
I have several pictures of the gun, including the myriad of proof marks. I just don't know how to attach them to this post.
This is without a doubt the prettiest gun I have ever owned. Any thoughts or suggestions would be appreciated. (Take it easy on the ignorant new guy
