Assuming everything else on the build and the load doesn't change, will swapping the stock or chassis change the load by more than +/- 0.1gr of powder and +/- 0.010" seating depth if I'm looking for the same group size and velocity? If it matters, let's assume it's any random non-magnum short action cartridge with somewhere between approximately 20-something and 40-something grains of powder inside.
