Older vs. New CCI-450s

[Old Navy]

I am just shooting the last 100 of a 5000 case lot of CCI-450s. I visually inspected the old vs. the new. There is a noticeable difference. The new are the top ones in the photo. Should I back off a little on the powder charge or just shoot them?

I have been to Lewiston/Clarkston. I remember their plant. I was surprised how small a town it was. Not to far from Orafino home of Nightforce.
