Back in the day, the 80s, I was to young to own a hand gun and my shootin' experience was limited to .22 cal rifles, shot guns, and on occasion an AR-15 from crazy Vietnam Vet Uncle on the Rez. Clearly, ammo tech. has sky rocketed and there are options galore out there, producing many ammo/caliber wars and such. But what ammo options were out there back in the day. Teach us some humility Ol Timey Experienced gurus. We seek an education in this matter.
