u have about ZERO chance of survival without body armor, even if your name is Robbie Leatham. How hard is it to have a .22 rifle, and just wait for your stupid ass outside of your job or house, hmm? A guy wanting you dead, or to take something valuable, and who is SERIOUS, is a lot more likely to have such a rifle and strategy than to have 2-3 buddies, with pistols, trying you from 10m+ ranges.
So what's the point of practicing at such longer ranges, on fully exposed, STATIONARY targets, hmm? wont be happening. You aint serious enough to wear body armor, so all such practicing and concerns are nothing more than plinking bs.
