Hello All, I need some pointers on using the Wilson trimmer. Every time I trim, I cannot get consistant lengths. Actually they are always too short. My 223 brass ends up being 1.740 - 1.748. I have adjusted the threaded stop endlessly. Always have used the shark fin attachment. 1 or 2 light turns, not short enough, too many turns too short. Any advice or tips.
