i used pistol powder/cream of wheat method with annealed cases on the first firing . . . i didnt want 100 medium pressure reloads o have to get thru before i went to the top end of performance
if i was going to go the other way and use bullets on the first firing to fireform then i would have the bullets engraving the rifling in annealed cases
be interested to see what twist you ended up with . . . if it was a target rifle I'm think it will have the holes on the side of the action for the rear aperture sight, some pics if you have time would be cool . . . R
