Your results don't surprise me too much as I've sectioned most of those bullets and, with the exception of the 175 LRAB, have found the jackets are all similiar in thickness and taper. I'm sure the lead hardness is similiar too as these bullets are designed for heavy game.

I am puzzled that the 175 Hornady RN would come apart. I would have guessed a larger expansion diameter and shorter penetration than the spire point. Things that make you scratch your head.

Seems father time is catching up to the venerable 175 Partition as the cup-n-core boys are catching up to it's legendary penetration ability.

The Sierra 175 BT continues to make me want to try it out this year.

Thanks for the info.
