OMG, I never kept any. I only shot groups when testing ammo or testing new guns that my gunsmith built for myself or other customers. For practice, I shot IR50/50 targets which requires one shot at each of 25 bulls.. A high score on that meant more than group size to me. But, I've shot more one hole 50 yrd groups than you can imagine. I didn't take pictures of them. They wouldn't impress the guys I shot against much, as we all shot plenty of them.
