N205 is obsolete and there is no QuickLOAD powder file for it. I recall Norma claimed they had scrapped some lots of N205 because of production problems with the formulation. It was replaced by Norma MRP, and Norma said 205 data was safe to use with MRP. That does not, of course, mean they are identical now, though. QuickLOAD, for example, has two MRP files called MRP and MRP2. This suggests that while the original MRP might have been close to 205, the current production may have shifted a bit. Indeed, the two produce significantly different pressures. As you found for 205, neither fits in the case, either.
