I'm not sure if this still applies, but the difference between Remington and Peters ammo used to be just for marketing. One store would sell Remington and the one across the street would sell the same stuff with a Peters label. IINM, this used to also happen with Winchester and Western ammo ammo. In the back of my supply of reloads there are some old white Western AA boxes, but most are Winchester, I've don't shot R-Ps.
