I went to the range and shot these groups.
5 rounds each @ 100yds
123SST's, Leverolution, Hornady brass, Federal 205's, 2.270" COL
All from bipod with rear bag.

I'm attaching a pic showing all four groups and I can post individual groups if you need close ups. I'm still fairly new to the load development game so I don't have everything down pat quite yet. I'm fairly confident that we're looking for minimal vertical dispersion, and not necessarily concerned with horizontal dispersion at this point, correct? The charges from left to right: 30.3, 30.8, 31.3, and 31.8. To me, it looks as if the 30.3 and 31.8 are the charges where I'm getting close to my node, agree? The outlier shots in the first two groups were all on me (1st shot of 1st group and last shot of second group, pulled both anticipating trigger break, still getting used to the new two-stage). I'm at my max COL so I can only shorten that to maintain use of the magazine. I've got light ejector marks at 31.8 so I might be able to get away with going up to 32.0 but wouldn't feel comfortable at all going above that. I don't have a chrono or means by which to measure pressure. I know that there is some sort of computer program to use than can calculate ES and SD but I don't remember what it is. Any help at all would be greatly appreciated.
Thanks
