No , big Jim they don't. the 50-110 has a different base and rim diameter than the 50-2.5 Sharps. The 348 Win was based on the 50-110 case. The 50-1 3/4", 50-2.5" , and 50-3.25" cases are all on the same case rim diameter and base diameter. 50-90 & 50-100 are the same 2.5" case just different loads. mb
