[QUOTE="Fitch, post: 370859, member: 19372"] Thanks. I learned about the OnTarget SW here: [URL="http://www.6mmbr.com/ontargetsoftware.html"]OnTarget Software[/URL] Data from a load development session will look like this after it's been analyzed in OnTarget: [IMG]http://i22.photobucket.com/albums/b336/frwillia/55gNBTBenchMarkCCI400A-A.jpg[/IMG] The data for each group includes CTC which is the max center to center distance in inches and MOA, ATC = Average distance from the bullet holes To the calculated Center of the group. The max width of the group, the max height of the group, and the vertical and horizonal distances from the point of aim to the calculated group center. Looking at this target it's pretty easy to see groups 3 and 4 are about as good as it gets for a first pass at load development - in fact they are "good enough". On other targets it's not so easy to see. I fired these groups on December 16th, it was cold, windy, and I didn't have my chronograph, but I know this rifle well so I went ahead with it anyway. That little CZ is a heck of a good rifle. I want the 55g load for coyotes. I use 40g NBT for groundhogs. I'm out of time at the moment - my bride of 41 years is dragging me off to buy fertilizer for the lawn - the sun is shining, she's thinking spring and it's going to rain so she wants the lawn fertilized.
