James if your gonna say its not big enough, say something like it aing got enough energy, or its bullet is too small to create a big enough wound channel or the small bullet will probably fragmentate and not do the damage needed. Dont tell me it's not got enough TKO, what the heck is that. A TKO number of 10 is what ? 10 inches of wound ? nope. 10 lbs of flesh destroyed ? nope. 10 steps a deer will take before it dies ? Nope. 10 what then ? Understand what I am getting at. Its a made up formula, nothing physical like FPS or Energy.
