Dennis;

I use a Hornady tool (http://www.sinclairintl.com/.aspx/pi...uge__standard_) to find out how far I can seat the bullets out of the brass before they engage the rifle lands when I close the bolt. In my testing I get very good results with no pressure issues when there is a .010" gap between the rifle lands and the bullet. Hornady's manual has more detail (http://www.hornady.com/assets/files/...ion_gauges.pdf)
