I have a question for all you mauser experts. I just purchased an Argentine 1891 and an 1895. The 1895 has a pitted bore and I am wondering if I can convert either rifle to a 35 Rem. I would also like to know if they are sm or large ring? I believe they are in 7.65x53mm but are not marked. I was told they were 7X57 but that is not the case.
