My question:
Why wouldn't the best consistency of any rifle/cartridge/bullet combo be the same with any powder that can achieve the same muzzle velocity?
Maybe this was mentioned but barrel harmonics would be my guess.Different powders have different pressure curves which directly effect the way the barrel moves.
Shooters who are serious about the best accuracy buy certain powders that are“Tried and true” . They buy powder in bulk as well. (8 pounders minimum ). They buy bullets by the thousand and enough cases to last the life of the barrel. This is all in an effort to mitigate the effects of changing lots which effects harmonics and consequently having to repeat load development.
Or if you have minimal time to experiment ( like myself ) you also buy in bulk for the same reasons mentioned.
