I've been shooting A-Bolts since 1988 (7mm RM Composite) and it shot very good, took my first elk with that rifle. My father has a SS 270 that he has taken elk, mule deer and white tails with, shoots great. I now have his Composite Stalker BOSS in 7mm RM, it will shoot with any custom rifle I have. Never had or saw a trigger failure. In 1988, we rafted down the Deschutes River across from the Warm Springs Indian Reservation, my rifle got soaked during the trip and no one bought oil (I flew in from the east coast), I wiped the rifle off with a paper towel and went hunting.
