Both loads were tested by Tom Armbrust. The 7/8th ounce load was tested using a Federal hull. Average pressure 7333 psi average MV 1150 fps.

The one ounce load was tested in a Cheddite hull with a folded crimp but by using a roll crimp you reduce chamber pressure by an average of 400psi. It tested at 9006 psi (folded crimp- 400 psi for the roll crimp) puts the chamber pressure at about 8600 psi. MV is pretty good at 1212 fps. I shoot both loads in my Damascus Lefever F and G grades.
