The speedy method isn\’t that speedy.
I\’m not sure that link is going to work. I have problems linking things in these forums.
The video is called \”How To Accurately Determine Cartridge Overall length\” by Ian Wilson (there are other videos showing the same procedure). Ian shows you how to determine the Maximum Cartridge Overall Length (COAL) using a projectile of the proper diameter and a cleaning rod. Once you\’ve calculated that, if you have a comparator you can measure the distance from cartridge base to bullet ogive of the dummy round. That measurement to the ogive is good for any caliber compatible bullet you\’ll use in that rifle. It\’s not dependent on bullet profile. If you change comparators you\’ll have to measure the dummy round again as comparators are just that, comparators. They are not exact measuring devices.
