I have shot 9 deer in total with 60 grain Partition and only 1 with 53 tsx. tsx visually hit a lot harder. All 4 petals broke off aiding in energy transfer, only recovered one petal. But the 9 deer with 60 grain partion only required 1 shot each. And busted a lot of bone. I finally receoved a 60 part this year. Waited until the deer was perfect broadside and tried to put it through as much bone and meat as I could. Entered left side front shoulder, broke 2 ribs going in, took off top of heart, and bottom of lungs, broke 1 rib exiting, entered right shoulder, broke bone just below shoulder blade and recovered bullet in meat just before skin. Maybe 1 inch from offside skin. What a little performer.
