well your selections are narrowed down to makes like nef-savage-remington etc.nef rifles will be under 300 but there single shots.i do believe savage has one around 300 thats not a bad rifle.remington has the 700 adl for a little over 300.most of these bottom line rifles require trigger work and sometimes glass bedding to be tack drivers.but i think not matter what you buy your budget will be short for a quality scope,a rifle is only as good as the scope thats mounted on it.personaly i would go with a savage or remington bolt action rifle.if one of these with a decent scope on it is over your budget then save money a little longer.trust me when i tell you if you skimp and go cheap you will regret it down the road.a remington adl or savage(don't remember model number)with a quality scope,rings and bases,bypod and sling,figure on spending any where between 600 and 700 $ minamum.
