I bought a bulk of 1000 rounds, which came in two boxes of 500--or so I thought.
The first box had all Federal head stamps, but was short 6 bullets when I reboxed them into lots of 50. The second box had mixed head stamps, primarily Winchester and R-P, and had 507 rounds.
So, my order of 1000 was actually 1001.
Haven't had a chance to fire one of these rounds yet.
