Thread: Obtaining more information from your groups - overlaying groups

The cool thing about using these metrics is that a 10rd group at 100m will give you a good MPOI to adjust from, with some variation in that depending on the precision of the rifle - a .2MRAD MR rifle will probably need more than 10rd to get a really solid zero - and a "close enough" mean radius number to understand your true precision. No need to fire 30.

Note that a Tikka with a bullet/brass it likes will shoot very well.
