I liked all the posts above, with one exception. I didn't like the comment of "third rate gunsmith", that is a personal attack and think unfair since the man can't defend himself.State your opinions, experience, hypothesis, whatever just leave the attacks out.

I think the most beneficial aspect of the ackley'sis always overlooked.... accuracy. Its a quite well known fact that"improving" orchanging shoulder angleshas agenerally beneficialaffect on accuracy. Now we are talking incremental benefits so it gets glossed over bythe "sexy" claims ofvelocity increases etc.The fact that an improved shoulder can produce 1/2 moa groups opposed to 3/4 moa (for example) isn't sexy.
