Right, so I arrived at the square range today excited to see how/whether I could improve my scores at 10 15 and 25 yards with static groups. This was target 7, a 25 yard slow group of 10, after all the sight adjustments I made today:
Bear in mind I am no great shot, but for me putting 9 of 10 on paper at 25 using irons is pretty decent. Score of 78-0X not bad for me. Not as good as I can do with a dot, but for irons, ok.
I'll leave off all the cyphering I did in my overly-complicated spreadsheet, adjusting the sights and measuring changes in height to generate inches per click at various ranges...this might be interesting to one or two folks (maybe) but extremely boring to everyone else. I enjoy the simple geometry problem and working out the numbers. It keeps me busy.
Back to the plot: I did end up with a total of +30 clicks on elevation, as I think I have it dialed in now. I will measure the rear sight height and record that setting for CCI Minimags.
For windage, I have not cracked the code on that, and I have more work to do. Maybe in my grip? I was able to zero the gun on target left/right up/down (see picture), but that needed +25 clicks on CW in windage. When I got it home, I looked at the rear sight, and it had more curve on it than Marilyn Monroe.
So I backed all that out, and put the rear notch back to the center. I am almost positive it's me; moving the rear sight to the right a large amount may let me shoot zeroed groups, but I need to learn to shoot the gun with the sights aligned. I will work some with the pistol in dry fire and see if I can cure it. It's weird being a lefty you'd think I was going to shoot low and right (and I did, for years), but now I seem to be shooting this pistol to the LEFT. Which is odd, to say the least. It's possible it's the gun and not me, but I am not convinced. There's a chance I can get someone else to shoot it, soon, so if I do, it will help to isolate me from the gun, if they shoot it centered with the sight in the middle.
At any rate, I left the elevation alone, at +30, as say, and will revisit the range again and work on why I am shooting to the left or right.
A couple other notes:
I shot today with a top of front sight hold. I don't think I meant to, starting out, but it seemed that all those rounds I shot with my 1911 with iron sights, I just reflexively shot with that sight picture. Which I am ok with, as a 6 o'clock hold means I'd need to account for target size at different ranges. With TOFS, I just line my castles up to bisect the bullseye.
And with my corrected nearsighted vision, nothing in my iron sight picture is ever clear, really. Mostly it's all fairly fuzzy. My cataract surgery is scheduled for April. I'm very nervous but excited about that. Not least of which is they tell me my middle distance vision should improve vastly, as well as my field of clear view, once I get my new eyes. Looking forward to that in any event because my vision is a bit cloudier than it's ever been...getting old sucks.
Other thing is I am shooting all this two handed unsupported. I really need to revisit the concept of a simple low cost bench rest for doing this kind of work. If ya'll know of a cheap ($50?) portable bench rest I can get off Amazon, please post a link.
The gun is running great, up to 263 rounds to date. Another 105 CCI Minimags today; no stoppages, no malfunctions. Not a large sample, but I'm glad it seems to run ok. Trigger seems about the same, I'll need to get my Lyman out after 500 rounds, maybe. This 22 stuff is turning out to be pretty enjoyable.
