“What did the groups look like?”
If my faulty long term memory serves, the first round looked something like this.
(Please click on the picture for a larger version.)
The target was two feet across, and set 35 feet or so from the firing line. The center hole was made by the projectile with the traditional bullet shape, and the other four by the light wadcutters. I didn’t actually hit the exact center of the target, of course, or even the ten ring. But I figured you would forgive me a little poetic license in the interest of clarity.
I can’t say what the pattern looked like for any of the subsequent 49 rounds, as I was just firing at the paper to get rid of them. There were more holes than paper hanging downrange by the time I was done, so at least we know that ammo like this does a bang up job of tearing apart targets!
One would think that the lighter bullets would tend to rise above the point of aim, not fall below. So why did things turn out this way? Dunno. Maybe it has something to do with the turbulence caused by the projectile out in front.
