Only 2 come to mind that are accurate to 100yds and cheep 17HMR and 223/5.56 . 223 will take down any animal up to small deer no problem and the 17HMR is just a bad azz 100yd caliber .
HHMM I guess 7.63x39 would work and really it's the caliber your looking for .
You did not mention budget or action .
223 = AR , Savage model 11 hoghunter and many more .
17HMR Savage 93R17
7.62x39 Savage Model: 10 FCM Scout
Im starting to detect a pattern here
