Has anyone ever seen Hickok 45 shoot anything that he could not ring the 80 yard gong with? I'm not debating caliber here, only that for myself, more training and practice would not hurt.
That's a standard stationary target.... It's hard not to miss and get a ring... Have them shoot back at you while mortars drop, then try and shoot that same target.... Shoot, move, relocate... That is entirely different story, so again training is paramount for your survival... It wouldn't hurt? Don't be so nonchalant and passive with that, training will save your life one day... Stop stressing about caliber, get quality range time, end of story....
