You will have to shoot both to find out which shoots best from your rifle. However, if accuracy is no factor, be advised that neither of those two choices is superior for shooting Texas whitetails - a .308" 180-grain bullet has all the performance and MORE for such uses. personally, I'd use a 150 or 165 grain bullet on those small deer out there.

Of the two, the Corelokt is a controlled-expansion bullet and the Power-Point is a plain-jane cup-and-draw softpoint. The Corelokt will provide deeper penetration on heavy game than the Power Point, if both are the same weight and strike identical spots on game at identical velocities. I have nevere used either type in factory ammo, 'cause I don't use factory ammo. But I have had some EXCELLENT ACCURACY from Corelokt bullets in hadloaded ammo, in both .30 caliber and 7mm cartridges. The Corelokt is an excellent bullet, and the new bonded core Corelokts are bound to be as good as any other premium, bonded-core bullet.
