RE: Best COC Heads?
Of the species you listed, I've used the 100 gr. NAP Thunderhead on my AK/Yukon moose and the 125 gr. 3 blade Muzzy on my brown bear with excellent success. As for Cut-On-Contact heads, I'm now shooting the 125 gr. NAP Razorback but I passed on putting it to the test on a rubbed 9' brown bear last Sunday. I hope I'll be able to let you know how they do soon. I am impressed with their accuracy and I like the idea of the rotating head being able to slide around heavy bone (ribs) rather than having to punch through it. It's just a theory that I haven't seen proof of but it seems that it would increase penetration.
