Thread: How much is over fill in 223

As the "discussion" is regards .223 loads, if you guys permit I also have a question about it. So far everybody who reply has said BM2 is great for the 55gn, my question is, what is the "general public" using for projectiles weighing 65, 69 or 75/77gn?
I do reload sierras 65 - 77gn but still using BM2 for it, I achieved good groups but not "high" velocities in the way I see(2800ft/sec), please, any considerations? I am thinking in try BM8208 or 2208(09) for those projectiles.

Thank you in advance.
