Source for 32-40 Jacketed bullets for Win 94

I am looking for a source for JACKETED 32-40 bullets sized .322. We have tried the .32 special bullets from Hornady and Speer sized .321 but the cannelure is set to far down the bullet. This causes the loaded round to be to long to feed from the magazine in our Winchester 94. I want jacketed rather than lead because the barrel is somewhat rough and leads easily. Thanks.
