Just purchased a box for my .243, BC is different, recommended twist is different, same part number. Old box has higher BC and recommended twist is 1:9. New box bc is less (bullet also measures shorter oal) and recommended twist is less 1:8.
I have been shooting these for years out of my 1:9.25 twist (custom chamber) gun for years. Measurements to the ogive for both boxes are the same.
