I recently bought a Styer SSG 69 off GB advertised as NIB NOS. Today I was attempting to sight it in and twice had the same malfunction. First round out of mag CLICK, the first instance I re cocked the rifle and it fired. The second time I saved the round. It has a super tiny firing pin mark. Ammo is ZQI 147 gr ball. I measured the primer depth and it is not deeper than a handful of other factory shells I have on hand. I fired probably 20 rounds in all, no other issues. Any insight ? Call Steyr ?
