Nah, I'll disagree with this and the following post talking about BC drag.99% of the people in this thread couldn't even dream of shooting the difference in bullet weight variation.... I'll show myself out
When you shoot a gun using a load or bullet it doesn't like and then shoot a load or bullet it does like, you can shoot the difference. And that's the point. There are clearly bullet designs that are etched into hall of fame. Bullets that are easy to tune in any rifle. Bullets that ammo manufacturers choose for those "universal loads". The Federal GMM 77gr, MK262 type bullets, the 108 BTs, the 139gr Scenars. And then there's the bullets that are polarizing. They work for some people but don't work for others. The super pointy 95gr SMKs, 183's, etc. And then there's the bullets where you open the box and the plastic tips that are supposed to be in the bullet are floating around free from the bullet itself. The unannounced shape redesigns. The bullets that almost shoot fucking great but just have those GD fliers that keep showing up eventually. That justify the 30rd sample size argument.
You can shoot the difference between consistently accurate bullets and bullets that shoot well in one lot but don't in another lot, that change shape in new lots, that allow their plastic tips to fall out.
