Went out to the range to check the site in on my rifles after the move. I was on my 6th round and noticed something move - Hmmm I thought - looked around - nothing. Went back to the scope and saw somethign again. So stopped for a minute and just scoped the area. Was someone out there. Pretty soon 4 does march out between the target and the backstop - coming out of a little gully to the right. Looked around. There were two guys sitting about 20 ft away firing but because of the gully they do not see them. Absolutely zero fear. They head back over to the right and then after just mozying along they walked on. Again - It was like they were deaf to the bullets.
