Re: i need advise
Wallyworld guns often came in .270 caliber, maybe because they may not have been popular and the distributers wholesaled them cheaper. Regardless, there's not really any drawback to the .270, aside from possibly some ammo suitibility issues.
For your needs a basic sporter .223 would be adequate for hunting applications, but that price range pretty much precludes something New-In-Box these days.
Also, because of outside factors, the firearms market is inflated and somewhat in disarray.
I'd say your timing is somewhat late, and that taking your time and scouting out a lot of alternatives would likely be your best bet.
