There are a wide range of hornady XTP bullets the 200gr .400 Cal is popular in both 45 and 50 cal. with the right sabot. the 240 in 44 cal with the green sabot [44/50] and the 250 45 calin 45/50 sabot. The only draw back is they are designed for pistol use so loads of around 90 or 100 gr are best if you push them real hard they will come apart and considerably reduce penetration.
