Again, I appreciate the constructive feedback.
Nope, not intending on doing this. Just wanted to find out the info about it.
Nope, not trying to argue either. I just want everyone to consider all the information.
As I believe I can conclude: From the evidence presented In most instances the problems that occured from this were involved with the back of the 5.56mm shell exploding due to the diameter and shape of the shell not allowing the faster burning pistol powder to exit through the front of the shell and barrel quickly enough. It seems that the remainder of the pistol powder then exploded into the bolt, carrier group, upper receiver, lower receiver, etc.. and therefore destroyed and manipulate the insides of the rifle.
For anyone who reads down this far on the post, this doesn't look like a good idea to try.
Those of you who are experimenting with this, best of luck and please be careful.
Thanks, again!
