30 degrees and windy. 100 rounds, Speer Lawman TMJ.....100 rounds......flawless. 100 rounds....on target @21 feet and 30ft. I am very happy with the SR45. Wish I had room @50 feet, but you take what you can when that's all the room you have to work with. First couple of rounds the slide needed a slight assist (1/8th inch maybe) forward, but that didn't happen in the last 98 or 97 rounds. Second box of 50 rounds grouped about 3" @ 30 feet, but I'll narrow that down. It hurts popping off 100 rounds @ $22 a box of 50....But it had to be done. Now...time to buy more ammo.
