Don't let anyone shet you! Not all guns, (or shooters) get <.5" groups! WhileI have seen some people post pics of some really tight groups here, it seems that most everyone comming from the range just shot "a group that you can cover with a dime!" (BS! they convieniently never have the proof with them!) Most of these people at workI know don't go to the range except once a year! Natural born, gifted shooters, I say!
1-1/2" is fine for any hunting gun!
