Bought a box of Herters 6.5x55 at the Cabela's in Buda, Tx. a few months ago. Box says manufactured by Sellier & Bellot. Shot decently in a couple of my Swedes.....nothing to brag about. I reload. When I first resized the Herters brass, had distinct impression the brass was on the hard side and would anneal it before reloading it the second time. Fired that batch, no split necks, and have reloaded the brass again.
