Gentlemen:
I have an old German 1888 Commission rifle that is chambered in 8 mm Mauser and has Turkish markings. It’s been sporterized (somewhat) into a carbine with a stepped Mauser barrel and chopped original stock. It shoots pretty well for having post and notch iron sights and short sight radius, I have only shot mild hand loads through it, as there is no point in stressing a nineteenth century action. The action is quite smooth and has potential. I have thought about re-barreling the action and building a nice cast boolit sporter. Any thoughts on what caliber would be well suited to this action?
