RE: Poor quality firearms straight from the factory.
In my expereince most rifles take a bit of playing to accurize them. Little adjustments make a big difference at the range. Ammo selection really seems to make a difference as well. Not all rifles like to shoot all bullets in thier caliber. You have to find what your rifle likes to shoot.
I went on a major research kick a couple of years ago to find a new versitile rifle. I was not sold on many low cost/quality brands - I just didn' t like the feels of them. I looked at everything I could find except custom shops since they were out of my price range. I found a Tika that I liked but did not buy it because it did not " feel" quite like a Sako. Many trips to gun shows and gun shops later, I found a Kongsberg Rifle - Norwegan made - a bit cheaper model of the Lakelander (Swedish made). The inventor or the action and magazine won an engineering award at the worlds fair in the 1980' s for it - he also used some " space shuttle" coating in the bore that was supposed to quickly dissapate heat - on the Lakelander model only. It was written up in Guns & Ammo and Rifle Shooter - It is a good combination of look and feel. I do not have that model so I can' t attest to it but it sure sounded good. Long story shorter...I have done nothing to the rifle except play with bullet manufacturers and adjust the trigger from about 6lbs down to about 2 (fully adjustable and the barrel and action are floated and bedded) and it shoots sub 1 MOA if the operator can get his act together.
You can find them on the auction sites if you have an interest.
