It's BS. Replacing match barrels once a month? Holy Moley....how many rounds do you plan to shoot? If you are after coyotes, if you get off three shots at the animal, it is more than likely two shots over what most people experience. Barrels are ruined by repeatedly shooting them when they are too hot, such as when hunting ground squirrels or a huge town of prairie dogs without letting the barrel cool. Shooting coyotes should not be a problem here, since you may get only a round or two off at a time. I have a match barrel on my .22-250 with over 1,000 rounds through it. I never shoot over 20 rounds at a time without cleaning the barrel and have not seen any appreciable loss of accuracy.
