Do you FL size, NS only or partial NS?
A topic that is continually widely debated with a lot of "I believes" but very little actual measurements for concentrity and case variance in most cases.
For those that do not know German Salazar is a highly respected LR shooter in the palma, 1000 yard and other NRA disciplines.
He has a very good website and here is his articles index page (The Rifleman's Journal: Articles Index) that most should add to your favorities and spend some time reading his articles and discussions with other top shooters.
Anyway he spent some time actually control testing some cases with differrent types sizing methods. Here is his article.
The Rifleman's Journal: Basics: Resizing - Case Dimension Changes
You figure out what you should do and why?
Another good read is is LR primer study. He used a pressure gauge (Oehler 43) to measure the variance in chamber pressure by simply changing primers in a 30-06. Would you believe over 4000 psi difference.
The Rifleman's Journal: Primers - Large Rifle Primer Study
so loading manuals, and so called reloading software programs might be way off base as who knows what primer they used and should be used with extreme caution. Did they use the one with the most pressure or least pressure? You go the other way and you could have an 8000 psi difference.
Start well below, work up and your gun will tell you. Taking someone elses magic load and popping it into your gun might lead to a "significant emotional event" for you.
Anway enjoy and keep this for reference.
