I am having a heck of a time finding the right load combo for my 300 sendero. I am trying to shoot the horady sst 180gr. I have tried different col's, powder, powder wght, and primers. What I am wanting to do is use this bullet for my general hunting and shooting and save my barnes triples for the occasional hunt (expensive). If any one has any load data, it will be gladly noted. Oh yeah, the best that I can bring the sst's in is about 1.25".
