[QUOTE="Clark, post: 446388, member: 6600"] No ogive measurement for me anymore. I find the OAL [ cartridge Over All Length] threshold of touching the lands. I find the OAL threshold of unfired bullets getting stuck in the throat. I use as my load, an OAL half way in between the two, if I can. Sometime the bullet is not long enough or the magazine is not long enough. The normal max AOL for a 30-06 based length cartridge; 25-05... 338 Win Mag is 3.34", and that is often the max the magazine length is designed to feed from with some margin for cartridge tipping up on one edge of the base. I have loaded the 7mmRemMag for 2010 hunting, not at 3.34", but at 3.48" with 70 gr Re22 180 gr VLD moly 3025 fps which is 0.140" over max. Part of how I was able to get away with that was that it was a Ruger #1 single shot with no magazine. If I pull an unfired round from the chamber, there are definitely lands marks on the bullet, but the bullet does not get stuck in the throat.
