For me yeah. I had some work up brass, Win, that stretched after being shot once. After reloading them, the second time, I couldn't get some of them to go into battery and the ones that did got stuck in the chamber after firing. Upon inspection the ones that fired had a ring at the very top of the neck, like a crimp (I don't crimp my 308 rounds, single feed). Normally I resize every three reloads with Lapua brass, I wasn't expecting the Win to stretch so quickly.
Additionally, when everything is the same you get better precision.
