I shoot .25 A pretty thorough search on the net for a rat, crow,etc, knock down reset-able target, I can't find. There are some just like I would like but they limit the size round one can use to .22 and some say no more than 20 FPE. The ones that are appealing are the ones you have to hit in a 'vital' area to knock the target down with increasingly smaller kill zones you can put on the target as you improve. I found some steel targets heavy enough for an AR and you can knock them down but then have to walk the 50 yds or so to reset them. Not afraid of exercise but a bit inconvenient.
