Get Out And Shoot


It was a beautiful morning, here in Texas, so I thought I'd better hurry up and head off to the range to see if the AR 15 lower receiver I built the other day actually worked.

First things first, I loaded Blue Tactical into the truck along with gun stuff and bought some ammo, 5.56, 62 grain, out of Turkey. It was cheap, and that appealed.



Did the lower work? It worked flawlessly, with no malfunctions over several hundred rounds. Very pleasing. But here's the thing, my red dot sight (RDS) was zeroed at 100 yards for 55 grain ammo, which meant it was off for 62 grain ammo.



If I'd been a smart shooter, I would have used my not-so-smart-phone to look up ballistic charts for the ammo I had in hand and zeroed accordingly. To help myself, you, and all the world, I've included a chart in this post to save everyone a lot time, money, and aggro. 

People like LL, who have forgotten more about shooting than I will ever know, may laugh at this. But hey, we learn by mistakes, unless you're the Church of England, or the Administration. In which case you don't.



I got on, in the end, after a lot of unnecessary messing around with my RDS. But the main thing is, the lower receiver worked perfectly. It'll go with my new upper, which should be ready in a day or two. I'm excited by that.



Blue Tactical was excited by the gunfire. So much so that he had to have a time-out in the bed of the truck. He liked that too.

Shoot straight,
