Not much. Velvet's is chambered is 7.62x39. I had started out thinking I'd also get/make an AK, so they could share ammo. That didn't happen, but there can be an in-universe reason for the ammo choice, that being that Velvet hopes to force you to keep trade relations with your enemy open during warfare so you don't run out of ammo.

Calamity's nickname was 'deadshot' so I chose his coat colors for my grendel build -- a caliber intended for long range accuracy and effectiveness.
