I have a whole array of free targets that I print out for accuracy work and shot recognition. I figured I woudl share them all with you. What I myself do is print out 2 of each and make one a master copy and use that print to replenish my dwindling supplies. I print them out on 8.5x11 paper.
I have some cardboard boxes that I cut to 10x12 dimensions and use those as backstops for the targets. Also makes it sturdier against recoil blast for quick follow up shots. Enjoy and good shooting.
these two are my fave for practicing
