At 100 yards, 4 "clicks"up/down/left/right will equal one inch on paper.
That is the way that it is supposed to be on most scopes,however it is not uncommon for the point of impact to move a little more,or a little less than that.
Best advice... Get a bench rest or bum one from a buddy.
As long as it isn't the type of rest that clamps onto the rifle and prevents it from recoiling properly,as those types of rest can effect the point of impact.
