Off the topic on this post, regarding Win 209's.
Back story, I was shooting Sporting Clays in Scotland with two Retired engineers. Engineers being Engineers after a round of clays it was time for a cup-a 9 (tea). The two started asking me what primers I used for reloading. The previous year the two took a brick of Fed, Win, CCI, Rem, Ched, Nobel, RIO and Fio’s and mic’d each one, did a heat test, and a pressure test. When done the Ched came out on top for being the most consistent.
