We all shot other bullets before Berger's, no one stays with a bullet because it sucks, not every bullet fits every shooter! No bullet has been documented shot for shot more than Berger's!
If your results don't match the plethora of experienced guys why not ask why, there's likely a reason. I've seen a couple guns that stresses jackets so much a Berger would not penetrate like normal, not a bullet issue but that gun needs a bullet that can handle a roached throat or a guy that does not want to keep a gun clean. Guys are far more concerned about being butt hurt and telling everyone than figuring out the issue when they see non typical results.
