IMHO, someone who didn't know what the hell they were doing either built a gun incorrectly or operator error...as I stated..I have shot in temps over 100F..never had a problem..no indication of it in any way..even when I have "stoked" them up a bit...even with a “ cheap” Remington action…also have one in a mauser style action as well, fully custom from head to toe…but, being the red-neck I am, still prefer the custom shop Remington…sorry…was what I grew up with ..no place like home..

Do think the Rigby is an awesome caliber and for nothing more than nostalgia..might get the nod from me the next time I get the urge to do another .416...

As to the mention that someone would need more penetration than the Rigby or Remington offer..can't really see that...shot a cow elephant with a 400 gr Barnes solid ..went in above her right eye..out behind the left ear..hit a tree behind her about 40 ft and kept going...have shot buffalo where the bullet entered in the rear and penetrated the entire body..those loads were chronographed at about 2445fps...using RL-15...
