My engineer gene got the best of me so when I saw the original post I wondered if I should do that to my .223 - punch it out to be a .223AI.
Modeling the two cartridges in QuickLoad I don't see any differences (~50 fps more MV for the AI with a 55g bullet given optimized powder choices in both cartridges - all other things being equal) that would say one is going to kill a coyote (or any other animal for that matter) the other won't kill. No significant difference in point blank range. The benefit of the AI is that it will shoot over the counter ammo, but so will my .223Rem.
So, after scratching my head a bit, and noting that everybody else thinks it is a fine idea, I have to ask. Out of pure curiosity, what is the motivation to spend the bux to punch it out to AI from regular .223?
I'm just asking. If ya just "want" one because you "want" one, that works for me! I have a safe full of guns I just "wanted", and I want even more. But I was looking for a logical reason in case I missed one.
Thanks
