I establish bullet seating depth as the longest case base-to-bullet ogive distance that will allow the finished round to be stripped from the magazine and cycled through the action of my M1A. You need a bullet comparator and .30-cal. insert to measure the base-to-ogive dimension. You're measuring base-to-bullet meplat (tip) distance, which is less repeatable. I believe seating to magazine length is common among M14-type handloaders.I have a question, I reloaded some win 308 and realized they the c.o.l was at 2.520 when they were supposed to be 2.735. I used Accurate 2460 with a 150 grain bullet. Is this going to be a safety issue.
Big boy toys? Seriously? Yes, inertial pullers can be used, but collet pullers aren’t that much more in cost.… not everyone has the big boy toys...
