I have found that
A) If you insist one providing exquisitely precise powder charges for extended distances,
B) You had better be damned good at making wind calls, or all that extra work becomes a total waste of time.
If your LR wind skills are like mine, a Dillon Progressive Powder measure works just great, making ammo that is better than I can employ to its full advantage.
Some of us, like Monte, have it; and some of us, like me, don't...
