You have a stock barrel? How hot are you loading these? Certainly not to 35K psi, 20 times..... right? Either that, or you need to buy a lottery ticket
why load to maximum if im just target shooting with it. I use the same barrel my gen 3 model 23 and 27 came with.
i use a low to mid range power load and i can shoot all day with no issues with ftf fte case failure or any others.
