By accident I stumbled on a really neat program for evaluating targets after shooting development loads. In the past I'd used the "Point Blank" free software but in order to store targets you have to make a bunch of manual measurements, each from the "offset" from point of aim.
This program is available here. [url]http://www.ontargetshooting.com

Three levels. The original version is a free download. The second release has a 15 day free trial and can be purchased for a reasonable fee. For the really anal, they also have a "Full Meal Deal" that allows one use info gathered from the OCW load development method.
Here is a target I ran through the "free trial" program and I have to say it's as easy as it gets. Scan the target into an image file, open the image in "On Target", and using the cursor place the bullet hole circles around each bullet hole in the target. The program does all the rest. Max Height, Max width, converts from inches to MOA, shows offset from aim point (great for easy scope adjustment). Shoot your last target group, go home and scan. Run the program then go make the adjustments on the turret as you wish. Just make sure that you shoot the group at the range you want the zero to be.
(10 rounds at 300 yards. Grid is 1/2" Wide X 1" High)
When I excluded the first shot, after which I made an elevation change on the scope, the group measures up pretty well. Very little vertical spread.
What I found interesting was the ability of the program to quickly calculate an Average to Center (ATC) of the group. Even though a group is a little large, by how much would you really be missing the target with multiple shots?
What I found impressive is that the learning curve was less than 15 minutes and all the calculations are updated as you mark the bullet holes.
Just thought I'd share with all the other "info junkies" out there.
FWIW, I also did a quick analysis of the same target without the low, first shot. All in all, it looks like I just might keep this load in my "recipe book".
Here's another "project view" tossing out the one "flier
