Have had a Brush Gun version for 40 years. First rifle I bought on my own after turning 18. Kills deer very well with 200 gr Hornady spire points. Groups in the 1.25 range for 3 shots at 100. Sometimes a bit more, sometimes a bit less. I'm sure other bullets work as well but I started with the Hornady's and never found a need to look elsewhere. Have also loaded 158 gr jacketed pistol bullets for cheaper shooting that's easier on the shoulder.
The trigger pull on mine is a bit heavy but manageable. My rifle currently wears a Leupold VX2 (?) 2-7 but has had a variety of 4X scopes over the years.
I can't speak to factory ammo, I bought dies the same day I bought the rifle.
