I have a large quantity of .257 120 Gr Nosler Partitions that I purchased a while back when I still had a quarter bore rifle.
These were purchased as seconds from Midway. They are all shiny, and the tips look good. Of the sample that I weighed (20+), they are very consistent at 119.8-120.1 gr.
The only difference is that they do have cannelures. My understanding is that they were produced for one of the ammo companies.
I have 484 of them. $.75 each plus $10 to ship regardless of the quantity.
Buy them all for $325 shipped.
