[QUOTE="MagnumManiac, post: 1126113, member: 10755"] As I thought you would already have known the answer and the question is rethorical, the answer is fairly simple. Because the sweet spot is a combination of distance to the lands, velocity and barrel time, the easiest way to stay in the node is to bump powder charges, when velocity drops, back to the original velocity. Many years ago, I would chase the lands, but this only works for about 1 season, throat erosion gets too much at the end of a season, so I would set back and re-chamber, sure this worked, but It was costly. Nowadays, a barrel can last 2 seasons without being set back and re-chambered. Your assessment on throat erosion is on par with my own measuring, .040" after a full weekend match of more than 200 rounds is common, depending on what powder is used. Double base powders seem to be kinder on throats than single base powder. Cheers. gun) [/QUOTE]
