My friends and I purchased 10,000 rounds a few years ago. I shot up at least 2 to 3,000 rounds of that purchase and have had zero problems.
Tula usually shoots between 1.5 and 2 inches at 100 yards but last week I shot some tight groups out of an AR I just put together. I was sighting in a red dot at 50 yards. The first 3 shots were left but all touching. I adjusted the scope and shot a 5 shot group to zero that was a measured .3". I was surprised by the group and decided to try it again. Another 5 shot group went into .3".
Now this was unusual and not the norm but it made my day.
