Have a mauser 1895 sporter had it checked and tapped for scope it'svery accurate is it safe to shoot hornady light magnums in it?
Impossible for us to give a meaningful answer at long distance- this would require a hands on evaluation by a competent gunsmith. We do not know the condition, or even what caliber it is in. Take it to a gunsmith. IF it has already been examined by a smith, call and ask.
