Yea, what jibjab says. The bullet shape will determine the seating depth. You may be able to find the information you are looking for in the forum buy doing a search for the bullet you are loading. You can also call the manufacture and see if they have any info about the bullet you are loading (some do some don't) or some of the loaders here may share. Some will and some won't, don't take it personal if someone will not share their recipes it has more to do with liability than spite.
Most here have a lot to contribute as info goes and most if not all are pretty good at this, they been at it a long time. I think Ricard Lee has a second edition book on reloading that covers a lot of stuff if you happen to run across it look inside and see if he has something for you in there.
