Powder/bullet lot change

[huntsd]

Im about out of powder/bullets for the load developed here. https://rokslide.com/forums/threads/77tmk-in-a-tikka.404037/page-3

Happy with the results at 500 and 100. Am I looking at a significant difference when I the same load just with a new lot number for both powder and bullets or is this a reloaded “wives tale”? Will be running the same brass. It’s about 4x fired now. Also same primers

So the “right answer is to drop .5 grains of so on the new powder lot and work back up. Having said that I/we have used dozens of lot numbers of 8208 all with the exact same load. While I would suggest it, I just load as normal with each lot of 8208.
