The 6UM

[Holt stewart]

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.

Another batch showed up today. Will have the gun put together tomorrow and go get the first rounds down the pipe on Friday.

I’ll get some groups in ballistiX later, but did simple load development copying coal from Ryan and Form. Most likely will land on 66.5. 3 shot group I know.. Gun weights 9.6lb with can on. Pumped with how it shoots and feels. I’ll get some photos and specs later.
