RE: Core Lok 30 06 125 grains...anyone hunt with them? Get deer pass through?
For factory ammo, I would stay away from 125 for deer. I have shot several deer at close range with 150s (Winchester pointed soft points)and some of those did not pass through, so I doubt you'd have better luck with 125.
I recommend a partition style bullet. That way enough of the bullet should hold together for full penetration on deer.
Now, if you don't want a passthrough, they may be just the thing. Not my preference though.
