I want to do a ladder test for my 300 win with N570 shooting 215 bergers. Where would you start the charge weights and end . I have never shot N570 before. How far off the lands would I start. Thanks alot
 
This will vary depending on the case used.

In ADG I would start at about 75g. I ended at 78.5gr.

In Norma I ended at 80.7gr.

Both were about .060" off the lands.

These were not light loads but were not showing pressure on the cases, pockets started getting a little loose at 3 firings though.
