Just curious as to what this is:
The two on the left, compared to a normal bullet on the right.
These are my regular loads; 140gr Nosler Ballistic tips.
I did a bit of reloading on the weekend and found 4-5 of these in the pack of 50. All in the same box, have all been packed in together for a year at least as that's how long they've been sitting in the safe.
It doesn't spread like rust would between 2 steel items, it seems limited to the affected projectiles so I'm assuming it's something in production rather than something which happens over time like corrosion.
Almost like over-filled lead has leaked... What's the story?
