Sounds like much ado about nothing.
I have no where near the big game experience as many here but according to most, any decent 180 from a 30-06 kills elk. Like I said before, I've always assumed that the Interlocks were "high echelon" C&Cs.
Sure, I'd like to load partitions or accubonds but they are hard to come by these days and seemingly made out of unobtanium the way they are priced.
If a 180 Interlock will kill elk (and they are readily available and inexpensive) then why not just use them?
