Coffee,
While you CAN buy every barrel/cartridge combination the combination of varminting/deer/paper-punching may be better served by a .243 Winchester...if money is an issue and you're good about sharing your rifle with the kids. Regardless, you MAY just find that the combination of price, versatility and accuracy make these little dandies hard NOT to keep collecting--regardless of your money situation!
Welcome and start shopping around for more Handi/NEF deals, they're everywhere!
