Well, hornady brass for starters.

Beyond that who knows. Mfrs typically use bulk powders, not the canister ones you see on the shelf.
And sometimes from year to year they change the powder.
Use a chrony to develop a load that duplicates accuracy and MV of the factory ones, for your barrel, is the only way to really get close.
