If you were to take a standard factory action, and shoot it out of the box, then true it up- what would the actual accuracy difference be?

The obvious answer is "it depends". Every action is different, each one will be a little more or less true, machined a little better or worse.

So if you were to take 100 actions, leave them bone stock, shoot them out of the same theoretical barrel, then take 100 trued actions and repeat- what would the average improvement in accuracy be?

You could poke a million holes in this question but hopefully the main point is getting through.

Thoughts?
