You need a Lee Enfield .303, doesn't matter if it's sporterized. You can use that for hunting if you want. You're going to need a .22lr, probably a 10/22 Ruger. Some kind of shotgun, most people have remington 870's. Then you're going to want some form of precision and/or tactical rifle like an AR180b, Norinco M305, cz858-2, etc.
It should cost no more than $200.00 for your Enfield, $300 for your 10/22, and $500 for your shotgun. That's $1000.00, then you can spend anywhere from $400 for the M305 to $1400 for the AR180b, the CZ858 is around $700.00
