[QUOTE="HOT TUNA, post: 1574361, member: 95931"] I use a Redding Instant Indicator with a bushing that is the exact groove diameter of the caliber I am loading for to establish seating depth. I set up the indicator with a inert master case that I have seated to length for the jump to the lands I want in the rifle I’m loading for. The Redding Instant Indicator paired with a Redding T7 Press and a Redding Competition Seating Die allows me to seat with near dead nuts consistency. Usually within +/- .0005” or under. In my opinion most comparators are useless because they are kind of random to what the inside diameter of the inserts are. They are usually never a diameter that is useful for consistency which is groove diameter. I know there are a few machinists out there that can make custom comparators where you can specify the exact diameter of the hole you need. If I was to ever buy a comparator that is the route I would take. When you measure from the base of the cartridge to the point on the ogive where it is the exact diameter of the grooves of the bore... every single bullet you load will have the exact same jump to the lands. I’ve found when I seat this way and closely manage my charge weights I almost always end up with loads with single digit ES and SD with very little effort in load development. [/QUOTE]
