Yes & no. OAL in small volume pistol rounds, like 9mm & 40, with fast powders, like faster than W231, can be problematic. In the larger revolver cases with medium to slow burning powders, OAL just isn't moving the pressure needle much, especially if not loading to max. Of course something like a 148gr WC is NOT the same as a 150gr SWC, but in general, the heavy bullet data for lighter bullets works fine & OAL doesn't affect much. Load to the crimp groove. If the OP is using 200gr LRN data for a 190gr LFP, as long as he isn't starting at max, he should be fine.
