Jim, sorry I'm late to the party.
Roughly 80% or of the deer I've killed with a 270 W have been with the 130 H S P and IF I ever had a bullet failure it wasn't evident to me.
I shot a couple of bucks with the 140 HBTSP and they were too tough for my liking. They didn't expand as quick on 150-180 lb. WT.
I shot ONE buck with a 130 Speer boat tail. It killed the deer like lightning BUT it didn't penetrate the off side rib cage.! !
The deer fell over and the COLD air from its lungs spewed up like a fountain. Never saw that before nor since.
I have BULK packed Rem P S P C L from the late 80s and have been using them. They are HARDER / TOUGHER than the Hornady's.
All in All my experience demonstrates WHY the Hornady Ils are called the "Poor Man's Partition".
Good Luck
Jerry
