Perhaps I'm too picky, but I go by the saying, "Good ain't good enough.".
When I see groups like these:

Once in awhile a 150-200 yard shot presents itself. These smart ol' bucks
NEVER let ya get closer than that in the terrain we have around here. I've
passed up shots like that just because I wasn't sure of the loaded bullet's
capabilities. When I know, and I mean REALLY know, I have a load/bullet
combination that can be trusted to make that 200 yard shot, there will soon
be a trophy hangin' on my wall. One can safely take a shot like that when
sub-MOA groups are consistantly attained. But to be pleased with 3-4"
groups at 100 yards is definately cause to pass up that long shot -- never
want to just wound a magnificent trophy.
