1st you have to pick an accurate cartridge, if you're just looking for target practice, I just read an article, I'll rephrase what it said...."only a few rounds achieved any real popularity in target shooting" ie....the .223, 6mm norma BR, 6.5/284 norma, .308 (7.62nato). So certainly any of these would work, the .270 win has always had a reputation of being very accurate, my semi auto browning BAR touches holes at 100yds.

the remington action has always been known for accuracy, though I think recently I heard newer models aren't as good as the old ones? not sure. You could get a CZ in .308 maybe?

Can get a weatherby vanguard sub-moa.....



Certainly a heavier, bolt action would be more apt to get you better shooting than a semi auto I'd think. Sako's are known for being awesome, maybe one of those in any of the above calibers, not sure where they price though probably 1000-2000?

Top it with a quality scope, with some quality mounts. If using factory ammo, buy a bunch and shoot and compare. If accuracy is yoru goal may hav eto try differ brands and diff weights. My .270 loves 130gr from federal.
