I have two different boxes of Winchester 38SPL 147gr JHP and am wondering if they are indeed the same load.
The first is a ‘White Box’ with product number Q4266.
The second is a silver Super-X ‘Subsonic’ branded box with product number XSUB38S.
Interesting that the subsonic box also has this painted over and restamped lot number.
I have found this Winchester description of the white box load

The white box load is used by our State Police while the subsonic box also came from that source and held the same service loads however the usual box is the white box (this single subsonic box is the only non white box the officer has seen in around ten years).
Secondly, there was a projectile change a few years back from an exposed lead nose, hollow point to a hollow point with the jacket extending right to the hollow point. I think this was a change to the Winchester projectile line up rather than a choice by the Police. Does anybody know when this change took place?
