Don’t be too quick to go with too long a freebore. Been plenty of barrels cut with too much. Give yourself a short enough freebore to chase the lands a bit as it erodes. It’s counterintuitive but the long nosed VLD bullets require less freebore than conventional bullets, not more. Dummy rounds with all the bullets you’re going to shoot is a good idea. Have your chamber based off the one with the shortest base-to-ogive measurement, giving yourself some to chase the lands.
