[QUOTE="Mike Matteson, post: 2001086, member: 101791"] I am generally shoot belted mag. Most of my powder start at 70gr+ to start with. Using a reloading manual I will start with their lowest powder load and go up at .5gr load increase per round watching for high pressure signs. Once high pressure signs show up, I stop there. I also watch where the bullets are being placed on the target. Noting hit placements looking for the rifle flat spot. Then work around that for grouping. At that time I am using my chronograph checking on velocity. At that time working COAL. I generally looking for 3200 to 3300 fps velocity from those rounds. It's not necessary you have to shot at those velocity. There lots of rifles don't develop that velocity. I do agree that the highest velocity doesn't generally create the best groups. I use 264 Win Mag, 7mm Rem Mag, 308 Norma Mag, and a 338 Win Mag and a few others. Bullets types that allow for that type of velocity. I don't have to rethink about my bullet path, because they are all running about the same. The other is I hold my shots to 500yds or less. I generally use a 2 x 8 Leupold scope on my rifles. So I do believe chronograph as a needed equipment. [/QUOTE]
