Hi guys can you tell me what would be the loudest civilian centrefire rifle able to be used on civilian ranges in Australia up to .50cal 12.7mm our local range allows this but I want something that really has some kick and is the loudest - any ideas? whats gunner be louder than a .308? I want to buy something like a magnum rifle maybe a Ruger or Winchester - but want it have more bang for my buck!....up to .50 cal? cannot be a .338 lapua or .50 bmg..as they are restricted - so what else - something maybe for hunting down the track too - big bore and loud!. sounds good!!?
