To the OP, yes, your shooting is outstanding. Relatively few handgunners shoot this well!
Here's a few my target scans . . .
The first was shot standing/unsupported @ 25 yards . . . single action. The revolver was a 1964-era "flat latch" Model 36 J-frame. I'd just bought it and these were the very first targets I shot with it. A "keeper" for sure!
I make my own targets on the computer, and find that a square target, @ the ratio of 1" in black square size per 10 yards really sits well on the top of the S&W revolver sights. Thus the 25 yard target has 2 1/2" squares, and the ten yard target below it is a 1" square.
I don't normally scan my targets so I don't have a lot to post, but a ratio of a 1" group per ten yards is about right for me . . . though it was easier when I was in my 30s to "see" the best sight picture. LOL
I do compete double action with my S&W revolvers (steel and pin matches) and love the way they all shoot, much better than my bottom feeders!
BTW, on the above 25 yard target I was using .38 Special 148 gn wadcutters out of that little J frame snubbie . . . so I was aiming at the top square and the rounds "rainbowed" into the lower target. LOL
Below is the very first target with this little snubbie @ ten yards at the same session. A fine shooting revolver indeed!
The following target (5" black square) was shot standing/unsupported/SA at fifty yards with a Model 29-5 topped with a Holosight. I deer hunt with this .44 Mag and have for years and I was simply verifying the rig was still holding its zero at the start of the season. I was (and still is)! 1 13/16" group @ 50 yards . . . the best standing unsupported group I've made at that range.
This past season I was slowly coming down a ladder stand when a coyote passed behind my stand at 40 yards. I slowly drew the .44 Mag while holding the stand with my "weak" hand . . . and dropped him in his tracks @ 40 yards one-handed/unsupported. It made my day . . . I HATE those things!
FRANKLY THOUGH . . . I shoot most of my test targets at 10 yards, for the grouping ratio is generally about the same at further distances . . . if I do my job. Here's a first test of a S&W Model 1903 (5th Change) .32 S&W Long revolver I picked up last year. It was made in 1916 and I was trying various ammo in it. Obviously . . . it "liked" THIS load a lot. Distance: 10 yards . . . S&W made great revolvers back then too!!!
