[QUOTE="Rhett Crider, post: 2578951, member: 105034"] Needs to fit your magazine and fit your chamber freebore. Max COAL is trimmed case length plus bullet OAL minus case neck length minus bullet boat-tail length. This gives you a full bearing surface in the case neck. Using reloading manuals don't usually help much when you load out longer than SAAMI specs. I use QuickLoads and always start loads 10% back and work up watching for pressure signs. I also use the Hornady comparitor and start 0.025 off lands if I'm not longer than the Max OAL from the above formula. Depending on your chamber and bullet, you may end up with more jump or a shorter COAL than Max. [/QUOTE]
