Over 50 years shooting X course NMC comp I shot 30/06, .308 Win as required by Palma and 300 Win Mag for 1000 yards and if I could go back and do it all over again my cartridge would be the 6MM Dasher! I shoot 1000 here regular like at home and under all conditions the Dasher is the most accurate cartridge I've ever fired....bar none!!
