The 25-3 uses the shorter cylinder of the .45 ACP version (1.53") as opposed to the 25-5 and later 1.67" cylinder. I know that Lyman's 255 gr LSW is too long if crimped in the crimp groove and must be crimped over the front driving band. I don't know about your specific bullets. Since these are non-rebated cylinders, loaded ammo must be shorter than 1.53" when measured from the front of the rim to the bullet nose or 1.59" OAL - I'd allow a fudge factor so you are not right at the cylinder limits.
Start low and work up your loads, just as with any new loads.
Adios,
