I recently came into possession of this rifle that is stamped with Arabic numbers and writing so I wasn`t sure what caliber it was. After posting on other threads I got enough feedback to determine it was probably a 7.65x53. Last week I went to our local gunshow in St. Catharines,ON and picked up 2 boxes of ammo. 1 box is marked FM"SF" 7.65-65 and is in great condition. Despite the 7.65-65 mark it cycles through the gun perfectly and I feel confident in firing this. The 2nd box is a mix of 3 different shells. 5 are marked FYA 1929 HP and are clean looking. 11 are marked FMMAP 1947 SF and a few were turning green. I cleaned them up with a metal polish but there is some pitting in the brass. 4 are marked Norma 7.65 ARG and in good shape. My question is am I safe to fire this stuff and if so is any of it corrosive?
