A mono through the shoulders and stuff stops. I've used nothing but Barnes. Have shot GMX and they were accurate as hell. Haven't messed with E-Tips. They'll be a pile of varying opinions, but its all I shoot at game. I reckon if one day something escapes, I'll bitch.
I generally work up the Barnes to where I want it, then try to match ballistics with a target bullet for dinking around with at 1/2 the price.
.277 = 129LRX & 135SMK
.264 = 120TTSX & 123 Amax
That's my story and I'm sticking to it.....
