JB and that shrapnel guy know what they are talking about.

Speaking of the serpent's lair, I had the privilege of finding out why one shooter would dust so many of the few that showed up close or in the middle of that 300-350 range before I extrapolated with "hold under" or turned turrets: a ballistic reticle that he used with proficiency.
It provided more hits than the BC of my 75gr. A-maxes, at least til the wind died down on Sunday (I'm sticking to that)!

The other rule is proficiency; guys who dog shoot a lot are better dog hunters, period.

JB will lean you towards a 204, but I think most folks on a budget are better served with a 223.

Right now I'm toying with the idea of another fast twist 222 Magnum with both turrets and a mil-dot system, if only for the 'dogs....because I could be more UBER.
