My neighbors are dairy farmers and they use John Deere tractors. Their tractors will out-pull any other John Deere in the neighborhood because they adjust the injectors to get more HP than the tractor is rated for. Thing is the rest of the tractor is designed and rated for the original HP as delivered by the factory. Now these people have the sense to hold this extra power in reserve for "special" and "emergency" use and not push their equipment to the max all the time so it will last a long time, but if they continually ran it at 200% of it's rated power it would break down in no time at all. The same thing applies with riffles and every other kind of machinery. I do not push my rifles beyond their design parameters. If I need more power, I use a bigger riffle. Lord knows I have enough of 'em.
