I have much more variety of calibers/chamberings in handguns vs rifles, but that's because I feel that there's enough of a difference in regard to performance and accuracy vs rifles. For rifles, I stick to common popular calibers because they do all I need and at an extremely low cost. I don't need a .22-250, 243, 6 or 6.5 Creedmoor, 6.5 Grendel, 6.8 SPC, .300 BLK, .35 Whelen, .458, etc. Not saying those aren't any good, I just have no use for them.
The only calibers I'm thinking of adding are 10mm for a handgun and in the future a .350 Legend AR upper. I don't live in anywhere near the Great Lakes, where straight wall rifles are the only hunting rifles you can use, but the .350 appears to be a very easy to reload cartridge that uses .357 Magnum bullets. Can't ask for much more from a semi auto rifle.
EDIT: Upon further thought, when I look at the list, I could easily live without the .22 Magnum revolvers, .25 ACP, .32 S&W Long top break, .410 Judge, and Tokarev, but these are all guns I got either for the guns themselves or to try something different.
Something like the .22 Mag out of a revolver... I shoot it and after shooting, I would take a .32 revolver over it every day. The only reason I have the .22 Mags is because they're all single action revolvers with a .22 LR cylinder.
I'd rather have a .22 LR semi auto than a .25. Can shoot it much more for less.
If there were more guns and ammo options for .32 ACP, I would rather have that over .380, but until the day comes when someone besides just Kel Tec makes a polymer .32 ACP, I'm gonna keep my .380 LCP's.
