I may have already said this, but I'm not a fan of corelok either when I got my first deer rifle I went to a private range for their public sight in day with two boxes of it for my 30-06 they set me up with a guy (I was green, greener then I am now) dialed her in at 50 in 5 shots. Went to 100yards there was no rhyme or reason to it up down left right, all over the place. After 20-25 shots guy says idk what the hell is going on. He goes to an old timer there he comes over says son what you shooting, I show him he sees those corelok bullets and says to me son those things are garbage come back next week with some Feds or Winchesters and we'll get you lined up. Sure poop next week I shot 10 times at 100 yards and was in the money.
Seems like every other time that story comes up a person had a similar story
