I encountered the most entertaining range day ever today. I had 300 rounds of 40 and 50 .357 magnum rounds just because i keep some in my truck. Today I figured was as good as any to go shoot a couple hundred rounds. I put my holster on, and out the door I went. Once I arrived at the range, i grabbed my range equipment and gave them my DL to hold while I shot. I shot 100 rounds and then realized that for some reason my rounds were going left of center. I was shooting at a blue silhouette target. All of my rounds but 8 were still on target, and most of them were in the 5 ring. (highest ring on these targets, encompasses center of mass, and center of head mass). I took another 16 rounds and fired at the head. Again, left of center. I could not figure out for the life of me what I was doing wrong, so I began dry firing to try and figure out what I was doing, and analyzing each step of the firing process that I use. As I was doing this, two K9 uniformed officers walked into the range with two gentleman in plain clothes, whom I later found out were just their civilian friends. They moved to the lane next to me and began laying out their weapons on the line and ammo on the back counter. We started talking guns, and I mentioned the problem I was having. One of the officers, whose name was John, told me to go ahead and fire another magazine and he would watch and try to help. So I went ahead and fired another magazine, and still, my rounds hit left of center. He suggested I try to mentally focus on just pressing the trigger with the pad of my finger and not put as much of my finger inside the trigger guard, I tried it and voila, rounds went right where I wanted them to go. The 5 of us then began talking guns and gear, I let them shoot my gun, they let me shoot a couple of the guns they brought with them, and we agreed to get together and shoot again in two weeks. And to top things off, the gentleman running the range gave me 50% off of my range fees. What a great day!!
