Welcome.
Unfortunately what you may think it's a simple question is rather complex.
Factory ammo from any source with much volume, doesn't use canister powders. Further they swap powders constantly. So what you bought to shoot last month, and what you would buy in another month; may or may not have the same powder in it.
So while the velocity may well stay the same, the issues and harmonics can well be different.
Similarly, factory rifles are mass produced things with various states of wear on the machines that built them. So a Savage 10 in Creed last month and one next month won't be identical. You have to just figure out what yours likes.
Cheers
