Bob from Canada sent me this:
I have a sore shoulder this morning ! That 550 gr. is the one that mostly surprised me . You're right , make it fit the throat and forget the rest . I did also lap out the tight spot under the barrel band.

Note that Bob's original design called for 0.459" diameter but he later found out that his rifle prefers fatter bullets to fit the sloppy throat.
