The first and one of only two Speer Grand Slams I've recovered in what is now 30 years of using them was from a 5x5 bull I shot through the shoulders with a 160g and my 7mm RM.
Both shoulder joints were destroyed and the bullet was lodged in the far side joint, exposed just under the skin. The bull went straight down but required a finisher. That is the only one I've shot through the shoulder joints.
(The second Grand Slam was recovered last year from a 6x5 shot through the chest almost broadside at 411 yards. It was under the hide on the far side.)

No, I'm not a Ruger bigot - just an unabashed fan of their revolvers, M77's and #1's.
A good .30-06 is a 99% solution.
