[QUOTE="Trnelson, post: 1541073, member: 42308"] A reliable Chronograph is nearly required equipment for a reloader, just like go and no-go gauges. When I start a new rig I always start with the minimum published charge and measure what that yields with my magnetospeed, back in the old days a shooting Chrony had to fit the bill. That gives me a solid, safe baseline that I can work up from. I’ve had a couple of rifles over the years that have yielded a surprising velocity that didn’t make it any place close to the published charge weight data maximums. Modern manufacturing techniques have done a lot to capitalize on repeatability much better precision in production rifles. A smart guy realizes that it doesn’t matter much what the XXXXX manual lists as a maximum charge if you are getting that velocity with two grains less powder and stops while he is ahead. It isn’t fashionable to wear any part of your rifle in or on your face. Listen to what your chronograph is telling you. [/QUOTE]
