Probably, obvious noob question:
As far as the ammo for this weekend's toys are concerned are 223's and 556's interchange? Or should it be 556?
Then on the 9mm luger stuff is 115gr 9mm Luger ok or is a heavier weight bullet preferred?
Thanks guys.
My understanding is that normally people don't have any issues running .223 in a 5.56, but some people don't like the idea of running 5.56 in a .223. I believe it has to do with the higher pressures of the 5.56 and it is also slightly longer, I believe.
As for the 9mm, the heavier-weighted bullets are for the suppressed 9s because they are subsonic.
