I believe I have read enough threads on COL to keep my head spinning for a week..but I believe I fully understand the concept of it, as well as its limitations (magazine length, pressure changes, ect..)
My question(s) is once you do figure out your length from the lands and get started on your quest for that perfect bullet seating depth how do you go about ensuring you hit this exact number every time you seat a bullet? Do you NEED to have a comparator for this action? Also, would you measure after each and every seating to ensure this length isn't changing, or would the die do its job on putting the bullet where it needs to go every time?
Something else I would like to figure out, is what is the best method to actually figure out when your on the lands? Could this be achieved by getting a case to barely accept a bullet and then slowly close the bolt until the action seats the bullet for you?..and then measure what you get?
Im sill new to this and figured Id better ask before it gets any warmer out
