In WWII John Rigby III was shot in the head by a German sniper using 8x57 Mauser. The bullet entered his helmet at the center front and did 1 1/2 complete circuits around and exited center rear. Except for entry and exit it stayed between the liner and the steel shell.

When the Rigby Co. resumed ammo production after the war for their 275 Rigby round (a hot loaded 7x57 Mauser) they went from 140 grain spritzer bullets to 154 grain semi-spritzer bullets. They decided that better penetration was more important than 400 yard flat trajectory.

By the way Company president, John Rigby III, lived the rest of his normal and natural life with a visible dent in his forehead!
