S.Sumner; I had a chance to look in R.Ball's 3rd edition of "Mauser Military Rifles of the World" and in the Spanish section it jumps from the M1895 to the M1916 and doesn't mention the M1915 at all. It doesn't mean it wasn't made its just not in the book yet maybe in the 4th edition.

So many mausers and so little time!!!! There are 1,000 different mausers. I'm kind of hooked on the 7mm's. What more can i say there just as accurate as the swede's(but maybe a tad better i was afraid to say it) The 7mm is one of the flatest shooting rounds there is, its so good they copied the 30-06 from it. I still like my 6,5 swede but the 7mm is right there with it. Small bores are awesome too!!!!
