At this point, I'd almost be willing to fund some Folgers Coffee commercial action regarding this whole Berger bullets thing:
"We've secretly replaced this Barnes shooter's ammunition with some loaded with Berger Match Grade Hunting bullets and rezero'd his rifle. Let's watch, and see how he responds."
"Hot DAMN! That bull took a nose dive!! Barnes bullets, boys!!!"
"Sir, actually, we replaced your Barnes bullets with Berger Match Grade Hunting bullets and re-zeroed your rifle. If you'd been shooting Barnes, the wind drift would have taken your shot right out of the kill zone and into his guts, and the bullet drop at that range would have had you skimming his belly with your preferred Barnes bullet. You should have learned to account for drop and drift by now, but we knew you wouldn't."
"No schitt?? You switched my ammo? What the fuuck??? You been fuucking with my gun?? You son of a bitch!!!"
"There you have it, folks. Another happy Berger Match Grade Hunting bullets user."
