Update,
Peters is long gone.
Remington ownes the name and makes ammo with the Peters name. Newer Peters is probably not much better than Remington UMC and I would avoid it. If you can get Winchester or Federal instead, do so. I take no pleasure in this posting but I have lived within 60 miles of the Remington ammo plant for a long time and have lots of experience with their ammo and reloading components.
