I have a Springfield standard M1A, and living in Arizona just minutes away from the Ben Avery Range, I would like to get into these hi-power matches they hold regularly. My only addition I've done to my rifle is I've added a "trigger shoe" which makes the trigger 3 times wider and makes for a comfortable trigger pull. My question would be, is my rifle good enough for these types of matches? Are there matches just for rifles like mine without having to travel to this big match I've heard of in Ohio?....I feel the Springfield is a very good rifle, but with all these Hi dollar race guns out there will I just be shooting with no hope doing even marginally good?...The Ben Avery Range has a long range portion, I have shot basketball sized groups at 400 yards....good enough or no?....
