I MUST BE VERY LUCKY THEN, I have had 3, one being a magnum and never had a malfunction that wasn't ammo related (ie. dud primer).
I know some people have had probelms with them, most of those people would have problems using chewing gum as well.
Inspect your front sight as well, make sure it isn't bent. Try different ammo. Does it shoot decent groups, even though the point of impact is skewed? Or does it just spray all over the place?
Lastly mount a scope on that rifle (as God intended) and see if it works better. If no luck call Remington
