While not broken in yet, it has so far kept 10 shots within a 3" circle @ 20yds freehand using a variety of different ammos(7.4/7.9/8.5/10.5).
I bought a refurb .177 95(springer) off a well known warehouse site and have so far been very satisified, but due to weather and work, haven't shot it as much as I'd like to. Hatsan did the refurb repairs and included the fix and repair paperwork with rifle to show 937 FPS, so I'm happy. Only thing I've done so far to it was a re-disassemble and use (blue) Loctite on a couple screws and mount a Burris 3-9x40 Rimfire scope. While not broken in yet, it has so far kept 10 shots within a 3" circle @ 20yds freehand using a variety of different ammos(7.4/7.9/8.5/10.5). When it gets warmer, I'm going to set up my shooting table to get a better/steady hold to tighten up the groups and stock up on some other different weight/brands of ammos to see what it really likes best at around 25/35/50 yards.
Not entirely off topic but my Air Arms S510 Xtra Fac .177 was purchased as a refurb from Pyramyd and it is still going strong with no more than a barrel cleaning after 4 years. PS I plink with this rifle a few times a week in my man cave and when weather permits in the backyardRefurb does not necessarily = poor quality when you get lucky like I did it may have been returned because of buyers remorse
