What shot size are you not able to get in 12ga in B&P loads?
I shoot 12ga and 16ga B&P's #5,#6, and #7 have not had an issue getting them.
I just recieved a pallet 105 flats. 60 flats were 12ga, 40 flats #7 and 20 flats #5. 45 flats of 16ga, 30 flats of #7 and 15 flats #6.
As to the Fox chambers you are spot on.
