You can make a target last many rounds. Just choose a specific location of the target and make it your new bull's eye. The other people at the range may think your missing the real bull's eye or that your all over the target but who really cares, your there for you right? In fact another fun thing is to pick a few spots and rapidly rotate from one to the other. Once again to someone else looking on it would appear your shots are all over, but you know exactly how close they are to where your actualy aiming.
Now if your ego is important, well then you need to replace your target every time you chew up the bull's eye, or miss it a couple times. Then you can save it to brag and spend time hanging up a nice new pristine target. I personaly don't plan to save the target or show it to anyone to be admired, and don't care what the next guy over thinks of my shooting when I just pick a new point of impact on the target and he thinks I am missing. Iwould rather my spend time shooting or leaving, not tinkering with paper around other people using guns. Those enviroments eventualy have accidents, and the less unnecessary time spent around Average Joe while he is shooting the better IMHO.
For example when shooting a man shaped target and you wear out center mass which is usualy it's bull's eye, try the head. When the head wears out try the groin. If that wears out pick a knee or shoulder etc. Or you can spread it out and include multiple, it does not have to be a spot you would actualy shoot in self defense, it is a paper target after all. Try like left shoulder, right shoulder, head. Pick a bull's eye for each and try to hit it. Or knee, knee, groin. It is the skill your practicing, not the location on a piece of paper. Or maybe you want 4 points of impact. Shoulder, other shoulder, knee, other knee. Switch up on the order. Maybe left shoulder right knee right shoulder left knee. Once you run out of those spots you got a new empty paper area between center mass and groin, use it. Until the target is about to be cut in half somewhere you can find a new point of impact because most targets have patterns or something in various locations that make it easy to pick a new bull's eye. As long as you can tell how far off you are from your point of aim then it is still working.
Then again maybe I am just cheap and don't like spending more time goofing around setting up new targets than necessary.
