Don’t remember if mine is Rem or Win but I'll check. If I load them hot, the head separates in about two or three loadings. I suspect this is more because of the chamber (TC Contender) than because of the brass. The rimmed case might also tempt the die makers to make the sizing die on the tight side, thus reducing the life of the case. I bought a Lee collet die in an attempt to reduce the working of the case body, but the case necks are on the thin side and the die doesn’t squeeze them enough to hold the bullets tightly.
I finally realized there is no reason at all to load it warm. Its purpose is a nice light plinker and small game gun, so I load accordingly. If I need more power I use a 223.
Who sells plated 22 Hornet brass? I have never seen it.
