personally i was in your predicament a while ago.
trying to find a good , decent boltaction can get tiresome. theres to much variety. and with main attention on the rem 700 series (for the customization) there arnt a lot of well know competitors in the lower price range
ive had some experience with it, and like most mossber rifles ive shot its ok, but not consistent grouping, with say a rifle of the same class
some alternatives for you to consider, that i looked into
savage axis in 300-400$
Ruger American 400-500$
Remington 700 700-800$
howa 1500 500-600$
Now these were rifles i looked at, but i didnt find them appealing with what i wanted to do. then a guy on the forums suggested to me to look into the Howa 1500, and ive thanked him time and again for it
The howa rifles are base price 570$ (no scope)
but if you go for a Game king you get a scope+mount for 610$, they have other variations as well
But you get a rubber overmold bedded stock, a match trigger and a 10 round magazine on these rifles, which are very precise shooters.
the howa 1500 also re-branded as a weatherby 1500/vanguard, actually outperform the rem 700 out of the box. But if you took a rem 700 and modified it with better stock, trigger, scope,and bolt it would easily outperform a stock howa 1500.
now if your a first time shooter the savage is a good idea with its well known accuracy and dependability, that you can get new parts on if it suits you
but if your looking for something that is accurate and easy to shoot and operate, and do quick modifications to(no gunsmithing required) , id push you towards the howas
heres a pic of my howa GK 1500, with the 10round magazine attachment(5rds are available too)

well i hope ive helped you get a few more ideas to look into. but if your heart is set on the mossberg, i wont knock it, for its stats, but its not something id trust when going for higher ranges
