AI Shot Group Analysis
Upload a photo of your shooting session and automatically get group size (inches & MOA), mean radius and point-of-impact offset. No login, no account. Nothing is stored.
1. Print the target
Download the printable ApexLOAD target and print it at 100% / actual size – not "fit to page". Shoot at the printed target first, then take a photo.
We only process photos of our printable targets. Make sure all 4 corner markers are fully visible.
Understanding your shot group results
What is group size, mean radius and point-of-impact offset?
Group size (extreme spread) is the distance between the two shots that are furthest apart, measured centre to centre. Mean radius is the average distance of every shot from the centre of the group and is the more stable precision figure, because a single flyer changes it far less than it changes the extreme spread. Point-of-impact offset is how far the centre of the group sits from the aiming point, horizontally and vertically — that is the value you dial out on your scope.
How is MOA calculated from group size and distance?
One minute of angle covers roughly 1.047 inches at 100 yards, so the angular size of a group is the group size in inches divided by 1.047 and by the distance in hundreds of yards. A 0.8 inch group at 200 yards is therefore about 0.38 MOA. Because the calculation depends entirely on the distance, entering the true shooting distance matters more than any other input.
Why do I have to use the printable ApexLOAD target?
The four corner markers on the printed target give the analysis a known reference size, so it can convert pixels into millimetres and inches no matter how far away or at what angle you held the camera. Print the target at 100% or actual size — never 'fit to page' — otherwise the scale is wrong and every result is off by the same factor.
What does the photo need to look like?
Photograph the target straight on in even light, with all four corner markers fully inside the frame and no strong shadow or reflection across the paper. Avoid extreme angles and keep the whole sheet in focus; bullet holes should be clearly visible as dark openings rather than smudges.
Is my photo stored?
No. On this public page the photo is analysed and then discarded — no account and no login is required, and nothing is kept. Only if you sign in and save a shooting session to your diary is the image stored with your load data so you can compare sessions later.
