Up in Wetzel County the ol' corelocks are ones that you can find anywhere you please too, except of course for my 7mm-08 the WalMarts only carries those danged Winchester PowerPoints. Terrible haha
I've had great success with the corelocks, I recovered one from my 7mm08 last year that hit right between the hams through the spine and went the length of the body and was under the skin by the ribs. Perfect mushroom.
