I've seen as many BSTs (& NBTs) end with bad stories as I've heard good ones!
My youngest son & his best bud both hung up their 243s (80grn TTSXs) & they both are PILING THEM UP with their 7-08s with 120TTSXs. Regardless of shot angle or position, the 120 still won't stay in the deer! Blood trails can be followed by Ray Charles with Stevie Wonder holding the flashlight.
