So you had some HP ammo for the 45, but chose not to use it. Yeah, okay. I think some people call this "stacking the deck". Your test is invalid due to personal bias.When has life ever been known to be fair...
This was a real life personal test on ammo that I shoot on a regular basis in my backyard on test subjects
Believe me all of my handguns keep fresh quality HP rounds
I shoot a lot of 9mm/.357sig defensive rounds only though as it's only a couple of dollars more to shoot. Not so much in the .45
Why don't you test a 22lr against an unloaded 45? It would be about as useful a comparison as the one in the OP.
