Were you here last year? and for several years prior to that?
If you were and were listening, you probably wouldnt be asking the question.
So ill hit you square in the chest with an answer.
This has nothing at all to do with the excellant 3 shot group, which we now know wasent shot by the person many here thought did, based on the wording of the original post.
Nor does it have anything at all to do about the one who actually did, or the builder of the very accurate gun that did, or any of that, and everything to do with just the action used to build the gun.
And just last year, it would have been all about a totally different action.
Now that the best i can do for you friend.
