slugman,
Congratulations on the nice doe....she looks bigger than the 10pt. buck I took with my Martin Hunter recurve the 2nd week of Oct.
I've spent a lot of time at the range shooting various 45's that last couple of years. The 220, 240 and 260gr. Dead Centers shoot very well w/110grs. of Triple 7 powder. In the Power Belts the 225 and 275gr. aero tip and hpwork well with just aboutall powders and heavy powder charges. I've shot some pretty good groups using the Barnes 195gr. Spit fire too.
I was not happy with the groups I shot using the 200gr. Hornady SST's
This could be me too, because there are many on this forum that swear by the SST in the 50cal and I can't get them to shoot out of my 50's either. I get to many unexplained fliers when I shoot SST's and T/C's shockwaves.
Good luck in finding that perfect bullet/powder combination.
