Dave,
Your right, there will be some veration in seating depth with different shapped bullets. The good news is that most gun shoot about the same over a .005 to .010 range, the problem is that you don`t know if that range is just off that lands or with a .030 jump. I`ve never used a Stoney point gage for that reason. You may also find that different bullets will shoot more accurately with different jumps, and different powder charges. I shoot right outside my door so it`s very easy for me to load up 5 round and go out and shoot them and come back in and load 5 more. When trying different bullets I`ll load 5 rounds with each bullet with everything else the same and shoot them. I`ll then come back in and change 1 thing, powder charge, seating depth ect. and load 5 more of each. Finding the best load for a rifle is mostly trial and error but if you do it systimaticaly you can save alot of time.
