Anything under 30 SD in most hunting applications would be GTG in my book. Now for extremelong range target stuff that would never do. The ES and SD would need to be as low as possible then delving below 10-12. .
Also the bore condition is important on results. Was it a squeaky clean bore to start? Was the first shot out of the barrel one of the two problem children?

I see. I did fire some xm193 to practice getting readings. It was very consistent more so than my loads... for five shots anyway. I was happy with my results having no idea prior how I was doing.
The bore was fouled when I began my ten shot string. It had shot 25 rounds earlier in the day. I like to mimic actual hunting conditions. In this case most of my pdog shots will be from a dirty barrel.
My hit % last trip was good enough for me. Now it will be more fun knowing my speeds somewhat (not including temp and other variables)
Speed kills and with those numbers and a few more you can flat put the speed on them.

I probably don't know what I'm missing if I am, but a cheat sheet from Hornady's Ballistic Calculator website, with all the variables I can put in, and I should be a lot closer than just guessing. Muzzle velocity sounds great at 3661, but at 300 and 400 yards it isn't quite as impressive. Thats where most of our pdogs get hit at.
But these little 40 gr Noslers BT's should still have pretty good effect around the 2300 fps zone at that distance.
