There is a report from LdSH War Diary comparing the 105mm to the 75mm Sherman.

Muzzle velocity at Charge 1 is 650 fps. This is subsonic, and less than a conventional .22LR bullet. Does someone have the MV for the more typical 75mm Sherman round?

[cletrac (RIP)]

Muzzle velocity with the 7 bag charge is 1550 fps.
That single bag charge barely qualifies it as a firearm!

I am very proud to say that the Troop Sergeant in this report is my uncle, Sgt. Gordon Fraser Johnson, who was not only the Sgt. that was flown to England along with a Troop Officer (Lt. Stanley W. Phillips) to learn the workings of the 17-pdr, but was also the tank commander who was involved in the action at Bulgaria. He was later killed in this tank near Barneveld, Holland on April 16, 1945, in one of the last major combat engagements of the LdSH in Holland. He was posthumously awarded the U.S. Bronze Star in 1946 for this action; a medal I now have proudly in my possession after my father gave it to me for safe-keeping.
On another note I am very pleased to see the Strathcona War Diaries have now been digitized. Inter-library loans were discontinued a number of years ago between public libraries and the Public Archives of Canada, which made a trip to Ottawa necessary if one wanted to view the material. Let's hope more WWII material becomes available over time.

"ANTELOPE": Commanded by Sgt. Kendall, it had mechanical trouble on the Centre Line short of the Hitler Line. Was later commanded by Sgt. G. F. Johnston; it was exchanged for one of the first 17 pounders in the San Giustina "Mud-hole" and retained its name; was the first 17 pounder to "K.O." an enemy tank: a PANTHER at Bulgaria while working with the "Hasty P's" in October '44. Sgt. Johnston fought many gallant actions in this tank, perhaps none more so than that near Barneveld, before the tank was hit. Sgt. Johnston received the posthumous award of the U.S. Bronze Star; Tpr. Leverington also was killed. The tank was never replaced. (from the Regimental history “Lord Strathcna’s Horse (Royal Canadians) A Record of Achievement” by J.M. McAvity)

Back to the sources John, have you seen anything for 27th CAR (Sherbrooke Fusilier Regiment) after summer 1944?

The 75mm HE shell, while a fix round, came with three different charge levels. A reduced charge with 0.59 lbs propellant, a normal charge with 1.15 lbs and a super charge with 2.00 lbs. I don’t have the MV for the reduced charge round. The MV of the normal charge is 1470 fps, and 1885 fps for the super charge round.
