There's no doubt of some performance gain, but aside from the possibility of less case trimming, I've just seen no need when the standard case is loaded to it's potential.

My current favorite below.

MM, what is your load and what velocity do you get loading it to full potential? I am curious because I load 280 for my family's 3 guns with 22" barrels and all of them can only push 140's at 2900 MAX with careful increments to 270 pressures. And when loaded to near max 270 pressures, accuracy decreases and I found it more accurate along the velocities of 2790-2850. Now if I can get a "mild and accraute" 280 AI to toss 3000-3100 out of a 22", I'd bite the bullet because that's 200 fps and not reaching near high pressures to do so. Will a deer know the difference at 300 yards (my max), no. But at least I can talk smack to .270 win guys that my 280AI 22" is more efficient.

Thanks to some of the guys here for advice, I will tell my brother to make his a 280 ackley.
