some people recently had some "failures" with the 308 cal 180 grain interlock.
I would propose that any failure is likely due to poor shot placement.
What kind of "failure" are they talking about? Did the deer/carribou/bear/critter "run" after the hit? No "bang-flop"?
Or it could be its performance once it hits the animal. Lack of penetration or more destructive of tissue then used to. I personnally haven't had an animal move forward when hit properly with a 180g Interlock. So let's hope they are still the same.
