It's hard to be $4 for 20 shots.
Yes, the Mosin Nagant and its 30 caliber rimmed cartridge is a renowned 400 yard varmint gun. And a Mini-14 is the same as an AR.
.223 hard to beat? Easier than a red-headed stepchild... Go w/a .243. Affordable, accurate, comfortable, common popular necked-down .308 that bridges your interests. A decent Savage bolt in that chambering would probably be what I'd gravitate towards.
Her're the .223, .243 and the .308
