I know this has been asked, but I'm having a hard time finding it,in search. I have manuals, an older Hodgdon for example that don't list a COL for loads. Can you help me with understanding this concept?
1. If no info is given, how do you determine COL? W/o being dangerous?
2. Is there a formula for determining COL. Such as when you reduce a load 10% to get a start point?
3. I know to use my barrel to do a drop test (in leu of a case gauge) is there other equations or factors to look at? Thank you everyone for helping me to learn to think for myself.
