[QUOTE="RockZ, post: 307910, member: 5750"] I set up a lee reloader press and a lee prefect powder measure and clamp it to the bench. After reviewing my data, I set the powder measure up to throw a charge that results in about 200fps less than the max velocity posted in the manual or quickload , which is close to the suggested start load in some manuals and pressure test right there. Using quickload as well as reloading manuals I have come up with very conservative starting loads,although they may be a bit above the suggested starting loads, sometimes they are the same. or even less depending on my components. I also bring a battery powered digital scale with me as well. I shoot a round through the chrono and just throw progressively larger powder charges till I reach the velocity I want or see pressure signs. I am trying to find a safe max, not a primer blowing max. Takes 10 rounds max. I start at .010 off of the lands in the pressure test round. I then load up two rounds at a time of and do a seating depth test to see where the best seating depth is. Takes 10 rounds max After I find a safe max and an accurate seating depth,I load up 5 and shoot a group to confirm. If it looks good I use the ladder method to fine tune: [url=http://www.6mmbr.com/laddertest.html]Long-Range Load Development[/url] [/QUOTE]
