[QUOTE="Rheinhardt, post: 95030, member: 5142"] If your using any quality bullet manufactured by sierra, hornady, nosler the tolerance on the ogive is acceptable. That why I said you want to leave it a close to the lands as possible without jamming. Leave far enough away so as to compensate for some of the natural fluctuation in bullet dimensions. I've used this method for years and its documented in several brand name reloading manuals that this is where the bullet should be seated for optimal accuracy. I can refer you the specific page numbers in my Hornady, Speer and Sierra manuals if you want. I will give you this: if you are loading for any chamber that has an excessively long throat such as a rifle barrel thats had quite a few rounds put thru it or a military rifle barrel then you might want to seat to a standard OAL so you can feed the cartridges into the magazines effectively. I will also conceed that anyone seating bullets in this manner would be wise to check the throat erosion every thousand rounds or so to adjust seating depth as the the throat will wear from shooting. But as far as the *worst* way to seat...the worst would be seating way too deep, generating excessive pressures and possibly injuring yourself and anyone near you. [/QUOTE]
