A buddy got a new 40 for Christmas, and a 100 rounds of Win 165s. Its an XD a look down the bbl reviews some freebore and generally cast friendly chamber throat friendly features. About the brass though. I've never seen auto anything smoke cases,as in soot on the outside of the case, and never from a factory load. After a closer look the brand new factory cases appear to have some of the factory crimp left too. I only see 2 possibilities 1 the brass is just, maybe,too hard.2 the loads aren't generating the pressures nominal to the 40 Smith ,either because chamber shape or the light for cartridge loading. If this brass is hard it'll be short lived ,if not will using the whole chamber/throat raise the pressure enough to make the brass seal w/175s.
Work ups will be simple ladders to function then group w/Unique and I expect to be 75% of max relative to the load window.
In case it would matter the bbl is 392/400 and the factory"J's" were small at the case mouth. His mould drops WW at 402-3 and 178-81 over about 60 drops in a 6C.
Not really seeking help at this point because I've been reading 40 posts for 3 years just wondering about the Win brass appearing so hard in this case, not punny on purpose, as I've 9mm brass w the head stamps practically gone that don't act like this.
