1. Accuracy is rarely a given with factory ammo.
2. The gun isn't bedded.
3. Your scope is not for precision, but for hunting -up close.
4. The stock is not designed to shoot off sandbags.
5. The trigger is not for precision, but for hunting -up close.
When you say 'clean barrel', is it really?
Or does it have oil in it?
A-Bolts are nice guns but like any mass produced, there are plenty of things that can be done to suit them to your needs. If you had BOSS, you could tune your barrel to the ammo desired for better results.
The best gunsmith I know with A-Bolts(which are special to rebarrel) is

This guy does as good of work as anyone I've seen & his prices are so low you'll feel guilty(LOL).
Have him rebarrel with a non-brake BOSS(from Browning) & bed stock, & true up your rings, & upgrade your trigger to an aftermarket. Pick up a ~25" Harris bipod for field use. And dry your clean bore out with alcohol so that the first shot has atleast a chance of hitting what you're aiming at. Oil takes a dozen shots to burn out..
