Sure you have...maybe with something like this.
A few weeks after I bought this gun in 1990 and made up some 240 grain loads it was a few weeks before hunting season. I went down to the town range with one of those cardboard deer targets usually used for archery. I put an orange dot over the heart area. With as much concentration as I could deliver I stood upright with both hands wrapped around the grips in a modified weaver stance and slowly squeezed off 3 rounds. Without a spotting scope it looked like all The shots were clustered. I told my buddy those three shots looked good, Im not going to spoil it with another. When the line was called I walked down to see two holes touching and one just off to the side. Where the sights were adjusted was a few inches off the orange dot. But thats just adjustment.
I could not do that again. But I can get decent groups with if I concentrate.
As I age it becomes More and more difficult. Most handgun shooting I do is 10 - 15 yards these days. And with less punishing firearms like 1911s and lighter revolvers in less aggressive calibers.
