All this discussion of group shooting got my wife inspired to shoot longer range on paper today. We are just in from a group shooting session, where we set up IPSC cardboard plus an 8 inch steel, and shot at 25, 50, 75 and 100 yards.
My wife shot her Glock 34 with Dawson FO sights and a stock barrel.
I first shot my Wilson customized Beretta 92A1 with FO sights, which has been my primary training pistol the last few months. As a control, I also shot my Mink CZ with FO sights, and then my Coldbore Custom Glock 17 chopped to a 19 butt (stock barrel) with HD sights. My wife was using Aguila ball and I was shooting 115 PMC.
We started at 25 yards, shooting the cardboard head, and then transitioned to the body at 50 yards and out. We shot five shot groups, so as not to get too fatigued. We mostly had A zone hits to 75 and then it gets harder. Eight inch steel was high probability to 75, where we both went 4/4 in a row (with the Glocks) on the 8 inch steel. At 100 yards, it was very iffy, partly I believe because our 3 inch at 25 yard pistols are shooting more like 12 inch groups at 100, making an 8 inch target small.
The absolute surprise was that I shot better centered, smaller groups with the chopped Gen 3 Glock 17 than with the Beretta or CZ. The Glock trigger also seemed easier to press without disturbing the sights. Both very surprising as I think of the Glock as the least "accurate" of these three pistols, with the "worst" trigger. Part of my rationale for the Beretta and CZ has always been how accurate they are. My wife thinks this is hysterical, being a long time Glocker.
Very interesting experience, which we will need to repeat more. 25 yards targets seem very close after shooting at the longer distances. If you have access to a longer range, I highly recommend this exercise.
