Kris, what ppc available guns do you currently have?
Myself, I use a MOJO smith and wesson revolver for 1500 matches.
it's based on a model 64. many based on model 10's abound, most will shoot 2" from a rest at 50 yards.
for a semi-auto, I'm using a Springfield Armory 1911 loaded in 9mm. Currently using it indoors, but, when the temperature goes up oh, say another 60 degrees, I'll be testing match loads outdoors for 50 yd matches. I've currently put in a Nowlin 9mm match barrel that I've yet to test out.
I'm going to play around with 147 gr Hornady xtp's , but, I know I have a good load using Hornady 115 gr HAP bullets.
and, the great 45 acp is renown for accuracy potential at 50 yds.
