We had a gal that made them target sized about 2x3 feet. They are fantastic to pin paper to. No staples, just straight push pins. They made her quit doing it. The plastic wasn’t allowed. The range is within a BLM soil conservation district.
I don’t know why they would object. The bullets just make little holes in the plastic, which nearly self-seals.
They are terrific targets, because the sharp “vector file” printing makes perfect corners on all parts of the letters. You can choose from a huge number of clear, defined aiming points.
