I snagged one of these a couple of months ago. Here are some pictures and a crude attempt at documenting a pull down. This round really lives up to the hype. I like it and really like shooting 10mm through it.
The closest powder comparison that I had in stock was AA#7. The case was full if not compressed a little. Also has a very heavy crimp.
Adding pictures.
Edit... Powder charge weight is 17.2g

I can't say for sure on the powder being used, however the powder that comes to mind is the Accurate #11FS or the TCM powders...
