Probably dumb, but, if the bullet has one do you seat to the cannelure?
thanks

charge size. More important for pistol loads in my opinion.
My 310 GNR and 8MM GNR loads are .200" below the cannelure.

Most handgun bullets have a cannelure

and in most cases you seat the bullet to that. but that is not written in stone. In my 378 GNR I seat the bullet out well past the cannelure. It gives me a bit more room for powder without jacking up the pressure with the bullet seated on the powder.The cannelure is just a place in general to seat your bullet to.

I seat the bullet to where I get the best accuracy. Seldom is it anywhere near the cannelure.
Maybe I'm not so good to ask...

If I have the throat I usually use it up. You don't want the bullet ojive to push into the rifling. I have done that and actually pulled the bullet from the case upon opening. It depends on the projectile as well, it's sloping shape. I like to stay off the rifling but like GNR said, use the extra space to keep pressure down. Many times this helps accuracy as well.
