Precisely and I totally agree with you. Even the link posted by SAI says 308 168GR is safe to use. Next, I am attacked for being ignorant.
Your ignorance is not about bullet weight. I told you that. I'll say it again, just for you. Just because 2 loads launch the same projectile at the same exact velocity, does not mean they do it with the same pressure, or more importantly, the same pressure curve. This is what you fail to understand. Pressure, along with the curve at which they peak, is very critical in gas piston actuated semi automatic rifles. The M1 Garand, and Springfield M1-A in particular. This is reloading 101. If you do not reload, I'll give you a pass. But if that's the case, you should not be trying to argue a point you do not understand. If your post proved anything, it proved that.
