[Paladin2]

Pick your round for your purpose and then get a gun. Spend more on ammo than the price of the gun.

[Cobra64]

No, spend more on training than ammo. The ability to hit your target the first time will save on untrained, futile attempts spraying lead everywhere and still failing to hit your target.

Marksmanship is key.

Unsupported, seven shot, quarter size group, at 7 yards from a 1911.
