SO... while trimming some .223 Basic brass for my friend Danny... I decided to leave the trimmer set at 1.595" and try a couple of pieces of 5.56...
It is showing promise...
IMHO it will require a neck expand and a retrim, BUT brass is basically free... and maybe, just maybe a 1.592" trim would leave the brass at 1.595" after the expand (eliminating the retrim step), but alas I am only good at trial and error vs. "real Trigonometry", but maybe y'all want to try this...
AND MAYBE... This is why the .350 Legend is 1.710" and not 1.595"... to keep us cheapskates from doing just this.
Just pondering
