I'll AI sooner or later just to have a unique gun (around my home town anyway), and put an end to brass trimming.

FWIW a 75 Amax at 3050 fps is [bleep] handy.


Thanks, Archie.

22" tube on the Montanas, right?

Any pressure signs and what COAL, approx?

My goal was to hit 3000 with a 75 Amax so it looks doable w/o going AI, for now. Like you, I may eventually do it for brass stretch and shiggles.


It ain't what you don't know that makes you an idiot...it's what you know for certain, that just ain't so...

Most people don't want to believe the truth~they want the truth to be what they believe.

Stupidity has no average...
