One thing that I've failed to hear mentioned (besides 2nd and 3rd hand reports of accuracy issues) is whether or not the gun was tuned for the ammo. Out of the box the barrel could need a good cleaning - maybe even a lapping (my .22 LW 250mm and 350mm did, but my .25 and .30 Alpha's did not need anything besides a good cleaning of the protective greases).
What ammo are you using? And what speed? Most stock .25s will be shooting the 25gr .25s around 960-080 fps which is just too fast for them and groupings are scattered. Slow them down to 880 and groups tighten up.
Just like any other airgun you need to tune the gun for the ammo you are using or else it may shoot like poop. I've very good 50 yard groups in the huge Leshiy 2 thread but I'll post it here again if it helps. This is 8 shots in .25 34 gr pellets. 7 within close to 1/2" and one random flier.
