The 45/90 WCF and the 45/90 Sharps are dimensionally the same. The Sharps then and now had/has a quicker twist to stabilize long heavy slugs. The leverguns otoh usually used a 300 grain "Express" slug. Heavier slugs in the levergun are more limited by the maximum O.A.L. the rifle will handle to function through the action. Barrels are easy, action length is action length.
