Some guys say at least five shots,,,some say 10 to determine a rifles average.
Who knows who is right?..good arguments from all sides,,but in the end it is all about repeatability.
The post with the 3 shots from shooting sticks tells me much more than the other....it looked like 3 dead coyotes to me.
I shoot from bags,bench ,prone,off hand,crumpled up clothing items(including boots) and i practice all of these,,to know what my rifle and i are capable of...i sight to cold bore ,,,so i am a big fan of the 2 shot group,,cause 1 could just be luck..............X
