Keep trying on the ammo. I would go with blackhills or ultramax for a box and see what happens. I had to run a few assorted boxes through mine to get what I liked and it ended up being the ultramax in 50 gr nosler bt. Mine shot the wolf without sticking, I had to try it when I bought the rifle, but the accuracy was terrible. I have a few thousand rounds of it for my AR and I got a handi with no other .223 rounds in the house. My range is basically my front deck out to the woods ,and the hot tub makes a fantastic bench......What to do??? I need to start reloading because my range is that close. I say keep playing with it, I love the .223 handi. Fun to shoot, doesn't break my shoulder or my bank to do so. Good luck and let us know what happens.
