Hi, I have recently purchased the newly released 77/44 and it is shooting very poorly- 2 1/2 inch groups at 25 yards/ 5-6 inches at 50 yards with several brands of factory ammo (winchester, federal, hornady). I have tried both a Leupold 2.5 and an NECG peep sight so its not the optics. All I am expecting is a 3-4 inch group at 100 yards. I love this little rifle but wish it would shoot properly. I don't reload and don't intend to. Any ideas?
