In the analysis of a group, what part

[308sako]

In looking at numerous groups the question comes to mind: What part of the cululative errors does imperfection of the bullet constitute.

Meaning, if wind induced errors account for 40%, and loading irregularities another 25%, sighting or operator error some "Y" %; what "X" amount is due to bullet imperfection in the system represented by what we call a group?

Well on a calm day you can rule out the wind, but all the other variables could be hard to determine. As far as handloading procedures go, you can do your best to to get it wired and consistant, but what powder/bullet/primer/seating depth/neck tension combo shoots best from your rifle can sometimes be a roll of the dice. With the quality made custom rifles, they usually shoot just about anything well which lays the burden on the trigger puller.

Should be interesting to hear what others say.
