I used to use the 150gr core-lokt until I saw the price tag on 170gr federal then I bought up a bunch of boxes ($10.50).
I sighted in my glenfield and my win 94 with the federals, every bit as accurate, hits hard as well.
This December 1st and 2nd I shot a coyote, 7pt, and a doe with this ammo. The coyote had his shoulder shattered and on the 2nd shot his lungs taken out both pass throughs.
The seven pt was hit angling towards me, I shot in front of the left shoulder and exited behind the right shoulder taking out the lungs, piled up after 20 yards.
The doe was running with the seven and I hit her high in the middle of the body hitting the bottom of the spine (broker her back) and taking out her off side lung dropping dead, found the bullet in the hide on that side, here is a pic. In my opinion I think its up to personal choice both work exactly how they are supposed to.
