[QUOTE="Buzzgun, post: 3066208, member: 4715"] Don't worry about the cannelure, if you aren't going to crimp, ignore it. I'll assume you don't have the tools to measure overall length at the bullet ogive, this is the "poor boy" method for setting oal. This will only work for this bullet. Take an empty case fired in the rifle you are working with, needs to be a case that has not been resized, push some very slight dents into the case mouth so it will hold a bullet. Take the bullet you want to use and "color" the bottom 2/3rds with a sharpie or magic marker and barely seat the bullet into the case. Now, put the case and bullet directly into the chamber of your rifle and close the bolt. When the bullet touches the lands, it will push back into the case until the bolt is fully closed. Gently open the bolt and catch the ejected round. Look carefully at the colored portion of the bullet.....if you see scratches toward the tip of the bullet in the color, then you know the bullet slipped while you were extracting it, either repeat the process or push the bullet into the case so that the case mouth is even with the end of the scratches. If the bullet sticks in the barrel and doesn't extract with the case, push it back out with a cleaning rod, color it again and add a few more small dents in the case mouth to provide additional grip on the bullet. If there are no scratches, the bullet didn't move and is seated so that it is touching the lands, the overall length of that cartridge is the maximum length that bullet can be seated in that rifle........however, you should seat the bullet at least 10 thousandths deeper to start. Now, the problem with this method is that many factory rifle have a throat that is so long a cartridge loaded so that the bullet is 10 thousandths off the lands won't fit in the magazine.......in that case, I start working up a load with the bullet seated just short enough to function through the magazine.
