If you don't count .22lr, I have 3 factory rifles and all 3 of them are fantastic. My Tikka CTR is a consistent 1/2MOA shooter and the feeding/bolt operation are flawless. My Cooper is a good midweight traditional rifle as well. In the weight/price class of a Mesa, I have my Barrett Fieldcraft for that. When I was originally looking at lightweight rifles I was thinking I'd get a Christensen but I couldn't resist the allure of the Fieldcraft. When I say it's a $3000+ rifle at a $1800 price point I mean it. The whole setup is 6.75lbs with scope and suppressor on it, and what they did to get 5/8-24 threads on it with the flared 18" barrel was perfect for suppressor use.
I've owned plenty of customs and high end rifles, from my current custom to an Accuracy International AT I sold awhile back. So I do have a decent frame of reference on good rifles. You can definitely still get good factory rifles that punch well above their weight class, it just takes some research.
