Hey Bob!
GREAT report! One thing to note with the Barnes 250gr Expander... It looks as if it may have tumbled some along its path in the newpaper. When petals look like that(petals FOWARD), that's the only thing that could have happened. Likely, when it lost a petal it offset its stability and tumbled.
Those XTPs hold together WAY better than Hornadys chart would indicate don't they?
