Due to my old eyes (79) , very bad hand tremors and not so good balance , I have changed my way of defensive practice and no longer use paper targets.
I scatter fired shot shells on the berm and shoot at them at different points from the hip up to chin level at 3-10 yds. after drawing and one hand only and before the tremors can start.
I hit a few , move a few , miss a lot but always close enough to defend myself from them.
I scatter them high , low , right and left and never shoot the same one twice in a row unless I decide on a double tap which is seldom.
YES , I do pick them up afterward and save them for the next time.
I mostly use my G19 and a lot of times with the AA .22 kit on it.
