I'm not the least bit surprised as I've been seeing that kind of ammunition from all the major manufacturer's for over 30 years. It's for that reason and other's that I don't shoot factory ammunition any more. The problem you can see is only the tip of the ice berg. I've disassembled numerous factory rounds over the years and have found powder charges so inconsistent that it makes me shake in my shoes to think that some unsuspecting individual could have fired that through their weapon. Bullets that are out of round by .002", powder charges that run +/- as much as 20%, and seating depths that vary by .030" is enough for me to never risk shooting factory ever again.
To someone who doesn't reload a variance of .030" doesn't mean much. But as an example, a 9mm round that is seated .030" deeper than listed can more than double the chamber pressures from a normal 28,000 to over 62,000 PSI. Don't get me started on this topic. Factory ammunition is loaded to a spec. that is considered one size fits all. Whats even more is, many shooters think that higher priced top shelf factory is going to be a high quality product, nothing could be further from the truth.
