I guess I still don't get it. To jump the 10,000 CUP increment one would have to exceed the published load by 2 grains of powder. You exceed the maximum published load for any rifle/cartridge combination by 2 grains and things will undoubtedly get exciting. Again, what is the problem if one follows accepted reloading practices and published data?
Your example of substituting components is easily answered by following the accepted practice of reducing the starting charge by 5-8% and working up back toward the maximum watching for signs of excessive pressure or velocity. I can't make sure everyone that attempts reloading is not going to run into trouble. I can, however, stress the importance of following accepted reloading practices and published load data, and using a little common sense. Beyond that everyone is on their own.
