I make brass as some of you may know.
My brass runs 100% in BLK chambers.
It also runs 100% in 300-221 chambers. I've got a pile of case gauges made with every reamer out there for 300-221. Between rounds actually fired and cases tested, no problems.
Here's where it gets weird. It runs through some of the ssk cut whisper chambers. Others not at all. But there is no consistency in this in so far as we can tell. This leads us to believe that not all ssk cut chambers are identical to each other. If JD Jone's lawyer hadn't harassed us a month ago I would be inclined to figure out how to modify my brass to run 100% in SSK chambers. Instead I cannot in good faith supply brass to his customers. Which is fine because they can still get brass. They just have to pay more...
I've seen mention before of multiple ssk whisper prints because changes have been made to the original. Not match bolt action, or test barrel vs ar15 reamers, but actual changes. Can't substantiate it. Don't really know. Won't care. But those statements are out there.
