I found two in the clearance bin at bass pro, who even knew they had a clearance bin? Anyway, no one knew what they were, guy gave them to me for my display board. Any ideas? Yes, they are bullets.
Hard to tell what your markings are to know the exact headstamp, but it looks like the maker directly below this post. Is that a 'P' and stars on the side?
Just got home and looked again with my high power peepers. 1920 @ 6.00. Stars at 3 and 9. Maybe an A with some sort of squiggle at 12.00. The overall look is like the 6.5x54 Mannlicher-Schonaue mentioned above
