I've just finished looking at the U-105 listings at www.uboat.net (no hyphen), and I can't find you're quote. could you please post a direct link so we can read it?

It is actually to be found in the u-boat.net "members" section under "ships attacked". Exact text is as follows:
Name:Rodney Star. Type:Steam merchantTonnage:11.803 tonsCompleted:1927 - Lithgows Ltd, Port Glasgow Owner:Blue Star Line Ltd, London Homeport:London Date of attack:16 May, 1941Nationality: British Fate:Sunk by U-105 (Georg Schewe)Position:05.03N, 19.02W - Grid ET 7133 - See location on a map -Complement:83 (0 dead and 83 survivors).Convoy:Route:Fray Bentos, Uruguay - Santos - Freetown - Glasgow Cargo:7000 tons of refrigerated and general cargo History:Built as Rodneystar, 1929 renamed Rodney Star
Notes on loss:At 05.48 hours on 16 May, 1941, the unescorted Rodney Star (Master Samuel John Clement) was hit in the stern by one of two torpedoes from U-105 about 420 miles west-southwest of Freetown. The ship was hit in the bow and amidships by two coups de grâce at 06.20 and 07.46 hours, but remained afloat. The U-boat surfaced and fired 91 high explosive rounds and 22 incendiary rounds from the deck gun into the waterline. Shortly before the ship sank by the stern in 05°08N/19°15W at 09.30 hours, a shell exploded in the barrel which was tore apart and wounded six men of the gun crew.
The survivors were picked up after six days by HMS Boreas (H 77) (LtCdr D.H. Maitland-Makgill Crichton) and Batna and landed at Takoradi on 23 May.



While I don't know if any u-boat ever carried starshells (stock SH3 probably got that wrong) we do know from this article that some carried incendiary as well as high explosive shells, so I think that we should at least be allowed our AP ammo back (if not also starshells, which could for this purpose [though it is a bit of a stretch] be classified as incendiary).
