i've read lots of performance reports for the savage 12bvss in 22-250 and they were outstanding. 0.25" groups!
As far as outshooting a remington, who knows. my shooting buddy has a remington 700 BDL in 6mm with tapered varmint barrel. it routinely shoots .4" at 100yds. I'd be happy with that kind of performance from this new 243 savage. I don't think 580 for a target rifle is a lot to pay. The 12bvss is on a laminated stock, and all metal parts are stainless. in addition, the barrel is fluted with a nice recessed crown topping it.
Heck, my best friend has a .303 enfield action on a target stock with a match grade sporter barrel that shoots <0.5" groups all day and night with the cheap factory ammo available for it. He paid next to nothing for the components and made the gun himself (other than the work on the action to sporterize it).
I had a husquavarna 6.5 x 55 that would shoot 1.25 groups all day long with open sights.
In essence, there are lots of nice guns out there...
I do know i'd put my tikka against your remington sporter any day of the year. :lol: it cost me 420 out the door. So $$ per inch of group are really low for this gun!
