Fellas,
I was wondering...is there a commercially available .223/5.56 round designed to produce lower chamber pressures (50K PSI, I read somewhere here IIRC) created when you fire a 55g FMJ through a 7" pistol build?
Additionally, I have read that a 55-62gr bullet fired from any barrel shorter than 11 or so inches will go through soft tissue without tumbling, therefore not disabling an adversary as promptly as needed. Wouldn't firing a round with lower amount of power, reducing terminal speed (subsonic even?) enhance the terminal ballistics of the bullet, again, when fired from a very short barrel?
I worry about barrel and upper internals' longevity. But foremost, I worry about my face being blown off by excessive pressure causing stress on the upper and it blowing up.
If not, why? Is it not feasible? If it is, has anyone tried it? Lastly, if it hasn't been done and it can be done, it sounds like a great business idea, given the increasing popularity of the AR pistols.
I would like to hear your analysis.
