Size a fired case so that only 1mm of the lip of the case neck is sized, or use pliers to tighten the neck a touch
Insert a projectile so that it is just started into the case neck
Liberally coat the the ogive and bullet body with lee lube to prevent the bullet jaming into the lands and pulling back out again giving a false reading
Chamber the cartridge, then extract it. This is your Max COAL into the lands.
Repeat this three or four times to be sure.
I do it this way.

The episode you need is episode 23 dealing with just necksizing 308 ammo .More and more I am finding that every time I ask someone a question about reloading no one seems to be able to give a definitive answer.

So I know it will chamber OK .My brass if anything is short as it's the first time it has been reused after being fired in my rifle. It will be a while before I have to consider case trimming.The more I learn the more I realize what I don't know.I don't wonder many people just fire factory ammo. But where is the fun in that ?
colinbentley wrote:Thanks Supaduke. The recommended maximumlength is 2.7098. .My dummy bullet measures 2.704. So I don't appear to have a problem.Please no more advice as I am getting more confused by the minute.

I've got a .243 Sako 85 and plan to load Sierra 95gr Tipped Match Kings and 100gr SPBT Game Kings. COAL with the Game Kings is 2.725" and so I plan to load to 2.710", or .015" off the lands. So far so good.
The SMKs are a different story. Due to the long ogive, COAL is 2.925" and there is no way I can load anywhere near that with the bullet seated properly. The TMK has a very short bearing surface due to the long boat tail and ogive. If I seat 6mm of the bearing surface into the neck, the OAL is about 2.750". If I seat 4mm, it is 2.830".
From what I've read, Match Kings don't mind a jump, but what would be better: to seat the bullet properly with a .175" jump, or seat it out a bit with a .095" jump? I read the article below and this bloke was seating his TMKs to 2.860" - which leaves just over 3mm of bearing surface in contact with the neck.

So what would be best? I have plenty of magazine length, so that's not a consideration.
