We've used Northwest Targets for twenty years with nothing but success. They are cheaper for the bird and the freight!! In the past the owner has come to our club to help with problems we had with our trap machines. We're a small club so we only throw about 300,000 targets a year off five Pat Traps.
I shot at a little club about 2 miles from the plant in Salem, Oregon. We would take a horse trailer down and get targets. They were great targets out of a Pat Trap. They also make a heavier rimmed clay(pheasant), for use out of portable sporting clays machines. Northwest targets aren't any harder to break than White Flyers. The clubs around me in South Central Oregon throw Caldwell "True Flight" targets. Some people get the two brands confused. Thanks David.
