Well thanks Uncle Rug! ha I'm 67 young myself, and I too find that I like them running fast. I have several powders but plenty of H4350 and several others. The new R16 promises a whole lot too. I'm definitely going to start out trying the 150 TTSX. I am not a Long Range Hunter, and I prefer to just point and shoot. I have always tended to want to "hold up a bit" when the range is 300 and over. When I tried to use the +3"@100, I have shot "over" far, far more than I ever shot under.
