Safe to Shoot in a 7x57 Spanish Mauser M1916
I picked up a Spanish Mauser M1916 in 7x57 a couple of months ago in excellent condition (manufactured in 1922). It functions perfectly and I have run about 40 rounds of commercial 7x57 ammo through it with no problems. Yesterday, I picked up a bunch of 7x57 reloaded ammo at an auction (along with an interesting .32 caliber Astra 300 but that is a different story). I am wondering if this ammo is safe to shoot in my M1916. Each lot is marked with what I assume is reloading data (I know nothing about reloading). Can some of you with reloading knowledge advise if these different rounds would be safe to shoot? Thank you and I apologize for the long list:
