I used the sb when I first started reloading for my 270win.They worked real good on deer.When I tried the bts when they first came out they would make a much larger hole with more bloodshot meat in deer.
It seems that they made them tougher now.
In my experience this was it in a nutshell. Still shoot and buy sb bullets when I find them and walk in a wide circle around 1 st generation ballistic tips( black box with red,green,and white lable)..
