If you start .010 off, you will usually be happy with the results. As far as C.O.L. goes, Just make sure it fits in the magazine of your rifle. As someone mentioned in a different subject post, open your calipers to .010 and see just how long that is.

That is darn good information and right on the money!
Seating one caliber into the neck is ill informed.

Very experienced hunters and reloaders on these sites that give advanced reloading advise.
www.sinclairintl.com sells two tools to measure bullet seating depth off the ogive,a Stony point tool(now Hornady) and a Davidson ogive gage used in conjunction with a split neck case. I use the davidson because they are $12 per caliber and they work in establishing seating depth to the .001.
If you are interested in shooting consistant sub 1/2" groups, learing how to accurately measure your OAL in relation to how far you are off the lands is critical, and is nothing more than advanced reloading techniques....really simple stuff. MGYSGT's advise is really about as good as it gets.
Good luck!
