Hiya JoeL and as usual excellent shooting. I recall the sight pictures I had using my 3MOA c-more at the max indoor range of 75feet, at 300ft I really can't wrap my head around what that sight pic would look like. And correct me as needed,but with 115gr,wouldn't ya have a drop of about 1.7inchs at 100yds? so wonder if your dot was aiming a little north of the bullseye. Was wind noticeable out there? If ya try it again,anyway possible to pic or vid it ?,I'd be in awe again. My guess is that the red dot would appear to cover the bullseye and a foot of target in all directions. Unless aided by some additional magnifying optic to co witness the red dot. And my eyes haven't corrected to 20/20 in 15years,but still enjoy shooting within the limits I still can. Be well.
Adrian--
The B-8c bullseye is 5-1/2" in diameter, so a 3 moa dot just fits IF the dot is crisp and truly 3 moa in diameter. I've used a 12" square at 200 yards with this same sight.
As far as drop goes, I sight the guns in at 25 yards for a center hold, center hit. At 50 yards in bullseye matches, I hold 2-3" high for the .22 and 9mm at 1100 fps, and a little higher for the .45. That is at 50 yards. Your theoretical drop of 1.7" sounds about right for 50 yards, not a 100.
At 100 yards, and a 25 yard zero, I hold 8-12" high for the 9mm and .22. This is why there are two B-8c targets in the video--the top one is the aim point. I will move the lower target right or left to center the group if there is a wind. I don't ever change the pistol zero because these are bullseye match guns that I shoot demos with when I get bored!
The drop at 200 yards is challenging since air density and wind becomes the dominant factor. The first time I tried it, I think I put the aim point on a 2x1 stick 54" above the target. That was too high at altitude and I held below the aim point and shot a pretty good group. I've settled on about 45-48" starting point at 200 yards for the 9mm and duplicated the initial good results maybe 4 times with the P-09. You have to do that on a pretty calm day, however. Don't try 200 with a sloppy gun, either.
Shooting from a rest is a distinct discipline that takes some practice. I can't shoot as well from a Caldwell rest that uses both the dust cover and butt of the gun for support. I do better with the gun not touching anything and my wrists resting on a block with a soft towel. Anything to keep me from waving the gun around, but without constraining the gun itself. When I used a rest touching the gun, I find myself putting tension against the rest and pulling the trigger at the same time and it just isn't natural to me. I'm more sensitive to this than most folks because of the bullseye match discipline and practice. Talk about a gun free to move with any change in muscle tension, that's single handed bullseye.
My biggest problem in shooting these demo videos is that I loose focus after shooting a surprisingly good target. The target in the video above was the second five shot group for the day, and that was after sighting in the gun at 25 yards after shimming the sight mount. So, I was pretty cold. The first group was low and right, and not very small, because I was trying to hold at 6 o'clock on the aim point and that wasn't as precise as the center hold used on the video group. In other words, I got my 100 yard act together after five shots, then had four shots within 2-3/8"? At a 100 yards? Who does that? I shot three more groups after the video target but couldn't focus, so they were comparatively sloppy at 6-8". Not 4". That is why I decided to shoot the gong--which I had never done before because I thought it was too big and not a challenge from a rest, so I shot it standing two handed, which is definitely a challenge, and a position I rarely use these days, so I am not very good at it. I was quite happy with 5 or 6 hits out of 10 with no practice and no do-overs and no cherry picking the shots for a video.
Enough already, I have to get ready to go to the range for some rigorous bullseye training with the P-10F.
