For what it’s worth, my milspec .223 wears a 36 power Weaver. Yes it seems like overkill but when the kids and I get bored shooting the X out of the targets at the range. We have fun shooting the push pins holding up the targets. Great to see your shots with.
If I was to buy a 10 or 12 power fixed scope, it would probably be a Leupold 12 power. All my hunting scopes are Leupold. Chris
