[QUOTE="FAL Shot, post: 870173, member: 27328"] Manufacturers have to replace machine tooling on a regular basis. It is a good time to make improvements to their manufactured product, so the new product may vary from old lots. I use the Hornady COAL gauge setup, and that gives me the same jump to the rifling, no matter what happens to the tip dimension. However, an ogive change will probably change the BC or the bearing surface may vary, so merely having the same jump to rifling will not comensate for this. If a load is important, you buy a lot of bullets from the same lot. When you buy again many years down the road, a very good chance you will have a new load development on your hands. More likely than not, in fact. [/QUOTE]
