Got my .280 Handi back in 2000 when I got a Michigan elk tag....yup, dropped him in his tracks.
As soon as I got it, I put $120 worth of ammo downrange trying everything I could find. Everything shot really well out of it... Groups ranged from about .75" to 2"....but that is with the factory trigger pull which is ungodly heavy. A 3lbs. trigger would have put the groups 1moa I'd bet.
