Good deal J. Those individual 3 shot groups will often (though not always) lie to you. 10 kinda holds a rig's feet to the fire.

Doesn't matter much, but did you happen to let the barrel cool during the 10 shot group or just fire them without cooling?

John

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
