    I bought 100 of these 6XC cases to test because I have had good performance in 2 other calibers with this brass. I chamfered the case mouths (none were bent or out of round),no other case prep was done. Primed them with CCI 450’s and loaded them a tad light due to case thickness. In load development I shot 2 5 shot groups at .270 back to back. My SD is 5. Speed is very good and could be a tad higher, but why?? So, I took the rest thru the steel rack and the gun shot very consistently to a 1000. Thanks Alpha for very good brass. Time to get more now.

    Yeah, hope they get it back into their product line up pretty soon! It’s a PITA making SR-primered 6XC cases from 6.5 Creedmoor or 308 “Palma” brass.

    Yes, time to get more! But that first review was dated 6/7/2018 & I’m looking to order some on 3/24/2019 & it’s ALL SOLD OUT? If it’s as good as that first reviewer says I’d expect Alpha to step up production so it’s more available than for a very short time maybe once a year?

    Or give us an option to get an e-mail notification when it’s become available once more so we can appreciate what Alpha’s gone to the trouble of developing for us?

    I’ve bought and used their small-primered 308 ‘Palma’ brass & like it a lot. Would buy some SR 6XC too if it were available!
