You mean you never acquired gun stuff "backwards"? I had 400 rounds of 7 X 57 before I had a rifle for it (ammo given to me). I had 4 AR !% 9mm mags before I had a gun to use them in (I go them cheap and had plans). I have over 1000 rds of .38 Super and never owned a pistol chambered in it (99% reloads, inexpensive used dies, range pickup brass, my own cast bullets).
In life, strive to take the high road....It offers a better field of fire.
