I have a Mini 30 and It's not a tack driver but depending on ammo it's OK.At 50 yards I can shoot two liter bottles pretty regularly with iron sights. If you fill them with water and put the cap on tight they blow up real nice. It will drop a deer also with good placement. I've taken some heat for hunting with mine but but that's from the kind of guys that will take five shots at a running deer.Put one of those rounds in Bambi's boiler room and you're having backstraps tonight.
All in all I'd say congrats on buying a great gun.
