Don't rush into buying anything. Do your research and decide what you really want to do with the rifle. If it's only for 100 yards and paper then almost anything will do.
My favorite paper punchers/plinkers are my Mosin Nagant 91/30 (cost=$96) shooting Surplus 7.62X54R ammo (cost=$3 per box of 20) or my Marlin 1892C (.357 Magnum) I got that rifle used for $300 with a scope and good leather sling. (ammo cost=$5 per box of 50 because I reload)
A rifle in .223, 7.62X39, 7.62X51 (.308) or even 7.62X63 (30-06) are all fun with Surplus ammo available. Old Military rifles in 30 Carbine, 7.62X51, 7.62X54R, 7mm Mauser (7X57mm), 8mm Mauser (8X57mm) are all easily found and fun to shoot.
Lever guns in 30-30 Winchester, 35 Remington, .357 Magnum, .44 Magnum, .454 Casull or even .45-70 are also a lot of fun.
Bottom line, all are different, all are fun so I suggest shooting a few before you decide to buy. (not that it will be your only purchase!! LOL)
