I had a false start this am (LaRue mount wasn't tight enough...my fault) but I got a start on breaking in.
This afternoon was really hot; 102F with a slight crossing breeze...but I really wanted to shoot after resolving the mount issue.
I took two new sighting shots, then loaded 5 for paper. I ended up shooting 6 since I had a flyer (#4, most likely a flinch). I've never shot in this kind of heat, so not sure what the effects of rapidly warming barrel will have.
I adjusted the gas block at 1.5 turns from fully closed. This resulted in brass landing at 4 o'clock between 6-10 feet away. Examining the necks I saw no "denting" like I get with my factory Grendel Entry upper (non-adjustable gas block).
As I shot more (didn't really wait long between shots; cleaned after every 5 or 6 for break in), the accuracy became worse. The wind started kicking up more as well. I'll go early next Saturday and see if cooler weather makes a difference.
