Different throats have different profiles which cause different amounts of resistance which gives different powders different time to achieve optimal pressure for the barrel.

Try sealing the barrel in with some asphalt tree sealer and doing another workup with both powders. Years ago people found out that military 45 ACP ball ammo was more accurate because it allowed better ignition prior to the bullet entering the bore.

"Gorsh" said Goofy as secondary explosions racked the beaten zone, "Did I do that?"
