Very nice!
I went to 730 round with the first 6UM, it was toast. As you probably already know 66g and 60 off seem to be the pet load for the DTACs.
I started at 30 off and 66gr and it shot good enough on once fired brass that I didn’t really mess with it after that. I am a little puzzled how I lost 150fps, I’m no doctor but I would imagine it’s got to be tied to the throat growing and it’s more than likely the cause for the accuracy problems I was seeing. After I added a grain and a half of powder bringing them back up to 3120fps they shot ten in 2.1” at three hundred yards.
