BLG: Clyde, your experiences with the Core-Lokt bullets mirrors my first hand experinces (few) and my first hand observations (MANY!)!
The Core-Lokt bullet WILL do its job once that projectile enters the heart/lung area of medium size big game (Mt. Goats, Antelope, Mule Deer, Black Bear, Whitetailed Deer and also on Elk).
One of my sons Hunts with a Remington 700 in 25/06 Remington caliber - we found out it shot Remington factory ammo so well that we never did "handload" for it!
He has killed Mule Deer, Antelope and Whitetailed Deer with it.
My good friend Brad killt a Missouri Breaks Bull Elk (7X6!) I spotted for him with his Browning 25/06 using Remington Core-Lokts!
Hold into the wind
