Finally picked up my Lone Star Armory creed AR and did some load development today. It has a 22" 8 twist Brux barrel with High Pressure JP bolt and carrier along with an a adjustable gas block.
I used H4350 powder, Federal 210 match primers, Hornady brass and 140 grain Amax bullets. I loaded every 2 tenths from 40 to 41 grains. It seems the magic number was 41 grains of powder
There were some high pressure signs, but from what I've read, this is common on higher pressure gas guns
Slightly flattened primers and some swipes
Some brass damage
I'm tickled that the gun is a shooter. It just took awhile to get every thing in for the build. Now it's time to stretch it out to see how she does.

The guy shooting next to me yesterday is a long range shooter and uses SB scopes. He looked through the Mark 6 and was impressed. He was really impressed that this gas gun was shooting groups like his AI AW308. He wanted to buy it and told him it wasn't for sale. Took me too long to get this thing built.
