Same bullet
These strings were shot in a CZ Shadow II with a 4.89 inch barrel. The bullet is a 142 grain zinc FMJ flat nose. Our loaded 142s target a 129 power factor (910 fps). BA 9.5 is a strong candidate if you load your own with this bullet. This is chronograph data from that gun, not a recipe to copy out of context.
