I've had some experience with Cutting Edge Bullets, and on game it has been pretty positive. However, it has only been with their Raptor line of bullets in .224 and .308 calibers. I can tell you the 55 grain Raptor is a faster killing bullet in .224 than a TSX/TTSX and in .308 150 grain out of a .300 Win Mag it's too much of a good thing. Since the petals are designed to shear off they create maximum damage on whitetail deer.
I think the CEB MTH suffers the same way the Barnes X and TSX bullets have in smaller diameter calibers. The hollow point is too small and the bullets don't open reliably, and often act like a solid by just penciling through. Barnes solution was to make larger hollow points in the TSX line and to add a polymer top and call it the TTSX. I do believe CEB is correcting this issue with their Maximus line with a larger hollow point for more reliable expansion. I'd love to see CEB add polymer tips to their MTH or Maximus line of bullets.
I think it simply boils down to the wrong bullet for the job. CEB makes better bullets for hunting than the MTH IMO that work as intended all the time. However, I'm grateful that there are guys like Zen testing stuff all the time and not afraid to post the results good or bad. It definitely helps people looking for that bullet for a once in a lifetime hunt.
