Recently saw a barrel cooler $55 Amazon also read articles on ice water with a plastic syringe and a small hose followed by dry patches. Also Utah long range shooters tells me there's no such thing as barrel break in simply shoot it and don't look back gun work says the opposite Weatherby says the opposite. Serious push me pull me affect ie: who's right and who's wrong?? I've got all the right equipment no knowledge of the subject. Any advice?? Simply going to be test driving a new barrel for several rounds in the summer heat.
