Well, there's a few ways I could answer this. The first is with the choice of 3 different cartridges each chambered in a bolt action sporter: say a .222, a .30/06, and a .458.
But another way is to allow handloading to provide the versatility rather than different chambers and have 3 role specific rifles all chambered for the same cartridge, probably a .30/06. There would be a short handy CRF bolt action carbine with a variable low power scope like a 1-4X in QD rings and ghost ring and post irons. Next is a standard full length CRF bolt action rifle with say a 25" medium contour sporter barrel, and a medium variable power rifle scope like a 1.5-8X. My ZG-47 fills that one nicely. And finally a heavy barrel target rifle based on a 700 style action bedded into a fully adjustable stock and topped with a high magnification scope.
Another option would be to have a military style gas gun say an M-1 Garand, a scoped bolt action CRF sporter, and a heavy barrel target gun all chamberd for the .30/06.
