Re: seating depth problem
Ok, I'm new at this too, so it may be a case of the blind leading the blind here. I ran into the same problem. Then I measured the lengths (overall length) of several of my SMKs and they varied by a thousandth or so. I think its just a difference in the meplat in my case. Possibly the same problem you are having. I just get them close to the OAL I want the loaded cartridge and go with it. If you keep changing the seating depth then you are going to be chasing your tail I think. If you do it that way then you are going to end up with a different OAL every time you change. I just make them all the same and don't try to chase it down.
