For sure, when thinking about adding a caliber to your collection, check the availability and cost of : ammo, dies, bullets, cases etc. Know your comfort level, some calibers are an Easter egg hunt to find ammo/reloading components for, and can be frustrating at times. If you are into rare or obsolete rounds then that pain is part of the experience, and viewed as something positive to have something rare/unique, but if you are not into it, don't go there.
