I don't have a chronograph...yet. It's on the list and it's one of the reasons why I'm not looking to push the envelope on anything. That and I don't want to blow up my Pinned and Recessed S&Ws!
True Blue looks compelling. But small pistol magnum primers being unobtanium right now, I might have to put it on the back burner.
Your BE 86 recommendation looks good. Alliant has data for 9mm in 125 gr LRN which is a bullet I was looking at trying from Brazos Bullet Company. And it just so happens that the 357 data calls for Federal 100 primers, which Midway has in stock along with BE 86.
