My vote would go to a Ruger American rifle in .270.....Ive tried out alot of entry level rifles, and the Ruger is the best in price class IMHO. It does'nt come with a $40 garbage scope, like a entry level savage, mossberg, or remington, but if you spend $400 on a ruger, you then buy a bushnell banner, or tasco scope, and your total price is around $500...if you can afford a little more, then buy a bushnell trophy.
Your best bet, to save money though, is buying a used remington model 700sps or another rifle of similiar quality....but in all honesty, a ruger american is a step above a model 700sps, and is actually on par with a tikka t3 lite IMHO. I own a tikka t3 lite, and my ruger american is just as accurate, softer recoiling because the better pad, same light weight, and seems built just as good, or better. The beefy bolt on a ruger is impressive, and the only part of the rifle that seems entry level, is the plastic stock. The stock is functional, and does not flex or bend like a cheap savage axis, but it isnt pretty, but then again, in order to produce a $400 rifle that shoots MOA, ruger had to cut costs somewere, but even though the stock isnt pretty, it is on par with a tikka stock....only it costs alot less.
