When I go to the range, I always try to shoot some 5 shot groups at 25 yards for record. I keep track of the groups in a spreadsheet that has a separate page for each handgun. I try to always come home from a range trip with at least one group for record, usually I end up with 2-4 groups.
The recorded data includes group size, distance, ammunition used and the date of the range trip. If they are shot from a rest (I've only done that once with one of my handguns--one other time helping a guy zero his handgun scope) that is also noted.
Last time I was at the range I shot four groups for record near the end of the shooting session using an STI GP6 with American Eagle ammunition. The average size for the 4 groups was 3.5 inches. Largest was 4.4" c-t-c, the smallest 2.6" c-t-c. That gun shoots pretty well for me and it likes American Eagle ammo--which I am flat out of now. That was my last box.
Early last year, I had a Glock 20 at the range, and for some reason I shot some five shot groups at about 15 yards (somewhere between 45 & 50 feet--the range isn't clearly marked at that distance) although I usually shoot my record groups at 25 yards. I recorded 3 groups for that range trip, one with Blazer Aluminum was 1.3" c-t-c, two groups shot with PPU (prvi partisan) measured 1" and 1.4".
I saved the little one from that trip, in addition to writing down the numbers.
The above groups were all shot without any time constraint whatsoever and using a two-hand hold. When I shoot for speed, I don't usually measure my groups; I usually just shoot to keep all my rounds inside a given area. e.g. The 10 ring on a D-1 target.
