Several factors determine ho well ammo groups:
How good is the ammo (in that gun)?
How well does that pistol shoot?
How much aiming error does the shooter induce into the test?
For most of us, the aiming error is so large that we can't tell how one ammo compares to the next, or how one pistol compares to the next.
I recently bought some new bullets and wanted to compare them to my old, favorite load. I loaded three different powder charges with two different powders. So 6 loads in all. And I have 3 guns in that caliber I wanted to try the bullets in.
I had some cheap laser sights on the shelf. These cost less than $15.00 each (ebay, from China, mailed to the door). A rough zero was all I needed on each pistol, since all I wanted to do was compare groups.
To zero the sight, I just aim at the wall across the room and adjust the laser dot to line up with the pistol sight.
The test went very well. One of the loads clearly sucked, and 2 were better than the others. Very little aiming error.
I have one of these cheap laser sights on a shotgun I use for indoor, lights off competitions. It has been there for several hundred shots and still works and held zero.
If you want to see if 115, or 124 or 147 is best in your 9mm, this is a cheap way to shoot some groups that means something.
