I generally don't see many deer where I hunt. Plus, I tend to take 3-4 different rifles when I go, then not bring them again for several years, so it can take a long while for something to get a second chance. I have one rifle I've killed two with, one shotgun I've killed two and one handgun I've killed two... so as a consequence those 3 never go hunting anymore. They have to give all the others a chance.
But for rifles... my shortened at both ends .45-70
