I was looking for some load information for the 300BLK I'm eventually going to get put together and came across this site 300 AAC BLACKOUT (300BLK)
It has some good links in it, and seems very straightforward about the strengths and weaknesses of the round. For those considering the BLK, I recommend it.
One thought came to me while reading about 9" barrels with this round - for those into AR pistols, this thing could be pretty awesome. The SBR/suppressor thing is a little different, but there are some who like AR pistols although I don't.
The favored powder seems to be H110 for supersonic loads. I'd like to find some loads using Varget since I have a fair amount of that on hand, but haven't found any. The website above pretty well explains why the powder selection is rather narrow - it has to do with the really reduced powder capacity and the need to cycle the action properly.
It's a short but good read on the main link. Check it out.
I finally have everything on the way. The back ordered NO GO gauge is coming, the charging handle is coming, and I ordered some degreaser/cleaner to use before I hit the parts with KG Gunkote.
After much research and head scratching, I ordered a Badger 350 airbrush kit with the medium tip, two jars, and hose. It's a single action, so I'll probably be able to keep it cleaner than the DA types, and it should handle the heavier epoxy based Gunkote pretty well. I went through Amazon to TCP and got the airbrush for around $33.
I found that Brownell's either does not want to sell their airbrush very badly or they make a huge profit on them. The very same brush kit they market for about $90 can be found for less than half that without much trouble. This is the Paasche H model.
Also, if anyone is thinking about getting into airbrushes, I suggest you find the site "Don's Airbrush Tips", by Don Wheeler. He says he's a retired engineer, and I kind of wonder if he's the guy behind Wheeler Engineering, maker of some very nice gun related tools.
