Six or Eight Inch Steel Targets?

[CaliXD]

I want to get some AR500 steel targets for handgun shooting. I plan on hanging the targets so that they can swing, so six or eight inch circles seem like the best deal. Considering all factors, including price, why would you choose one over the other? Thanks!

i'd go for the 8. how wide is a human head and or critical mass on the torso? as long as you can hit one of those it doesn't much matter how accurate you get other than that. and if you want to make them smaller you just have to step farther back
