Sierra 90 grain HP will skip I am sure, as it will shoot through deer. Always felt the 85 Ballistic Tip was too tough for my liking as well.
The 90 grain Blitzking, 87 grain TNT or even the 75 grain V-Max or hollow points should work nicely.
the 90gr Sierra hpbt are rated for deer type game, I shot groundhogs with them and they always exited the groundhog, the first nosler 85gr ballistic trip were great for shooting hogs but I think nosler toughen them up
