Hoot4570,
The 108/49 is the bore diameter and is often seen on various 9.3 rifles.This bore dia.most often has a groove diameter of .362-.364".There are several options for bullets,most appropriate for normal shooting being cast bullets.Cases are often made fron shortened 9.3x72R, but I prefer original length(2.125-2.130") 38-55 cases, even though a little short,to save the longer cases.Rifles like this are a "Hoot" to load for and shoot, and I encourage you to do so.It would be good to post photos.
Mike
