[QUOTE="Steve Shelp, post: 173670, member: 22"] Qzilla, First of all forget about COL, IF the round feeds through your magazine at your given length. COL changes everytime you seat a different bullet in a case anyway. I've loaded for the better part of my whole life for everything from basic 100yd deer rifles to full blown competition BR rifles and never once looked at the COL of what "the book" said. Your description of how you actually inserted the bullet in the case and measured it is a bit confusing to me. I will seat a bullet long in a partial sized case. Blacked the whole upper ogive portion of the bullet and carefully put the case into the chamber (no primer or powder at this point) and guide it into the chamber by hand. Then close the bolt to fully seat the bullet back into the case. Carefully extract the case from the rifle making sure to catch it so the ejector doesn't toss it onto the floor. Take a measurement and repeat this process 3 times to make sure you gets 3 consistant measurements. If you don't, there isn't enough neck tension to hold the bullet upon extraction. Once you get 3 consecutive consistant measurements (within a couple thousands) then this measurement is basically your maximum seating depth period. The bullet is actually hard into the lands at this point. But I use this "dummy" cartridge to setup my seating die. Then make adjustments to back the bullet down some so it's not so hard into the lands. Normally a .010" difference is all it takes. This can easily be varified by using the same method and blacking the bullet again and reseating. Upon extraction you should get slight scratch marks from each of the lands in your barrel. I have used the dented case mouth method in a pinch, but there normally isn't enough friction to keep the bullet in place once you go to extract the case and measure. And you end up with different measurements each time you try to measure it. This is what BuffaloBob was getting at with the taper pulling the bullet out of the case once in awhile. If the base of the 110gr bullet is anywhere between 2/3 down your case neck and the neck/shoulder junction, forget the COL measurements. Even if it is a little deeper into the case body isn't the end of the world. Just means you have more throat to burn out before your rebarrel it. Make sure that this new length feeds through your magazine (if you plan on using it) and go shoot. Just remember with a shorter throat your old loads will run higher pressures now. So work up your load accordingly. Hope this helps. Steve [/QUOTE]
