I had a Nightmare Day a month or-so ago when I took three rifles to the range and it took the entire 2 hours I reserved for this range visit, to finally get ML #1 ready for Opening Day. I absolutely hate it when the tightest shot groups at 50 yards, turns out to be the worst of my bullet and powder volume selections, at 150 yards.

So needless to say, twice I returned to a lesser yardage range to resolve this issue, then back to the 150 yard target finally.
