I went to the range last night, and ended up with 5 rounds left on a box of 9mm, 115gr, Blazer Brass, so I put them in the mag, and the topped it off with 115gr Lawman. I really noticed the difference in power on the first 10 shots, then the first round of that BB went off, and the recoil dropped off dramatically!
If anyone doubts that the Lawman rounds are hotter, just load half of a mag with BB, AE, or whatever, and the other half with Lawman...you'll feel the difference!
I know this is nothing new to most, it was just an observation.
