You are somewhat correct on Russian T-34's.
The standard load outs were mostly HE rounds & a few armour piercing & 5 HVAP rounds on the 76's & 4 HVAP on the 85's. However this paragraph from a Russian book from this man Alexei Isaev Artem Drabkin who was in T-34's during WWII. Also mentions the standard load outs carried confirms your numbers on HVAP. However the crews determined by the mission requirements as to what they would actually carry though. So I would say HTC has taken the option of optional load outs as required by the mission.
PS. You will have to translate it.

Weaponry. According to the "Guide Service" the first task of 76.2-mm tank gun F-34 was "The destruction of tanks and other mechanized means of the enemy" (FOOTNOTE: 76-mm tank gun upgraded arr. 1940 (F-34) and 76-mm tank gun mod. 1941 (ZIS-5). Moscow: Military Publishing, 1943, p.3). Veterans tankers unanimously called enemy tanks as the main and most serious opponent. In the initial period of the war T-34 crews were confident to fight any German tanks, rightly believing that the powerful gun and reliable armor protection will ensure success in battle. The appearance on the battlefield, "Tiger" and "Panther" has changed the situation reversed. Now the German tanks were "long arm" that allows to fight without worrying about the disguise, "Using the fact that we have a 76-mm cannon that can take on the forehead of their armor with only 500 meters, they were standing in the open" (Iron) . Even piercing shells to 76-mm guns are not allowed in the duel benefits such as pierced only 90 mm of homogeneous armor at a distance of 500 meters while the frontal armor Pz.VIH "Tiger" has a thickness of 102 mm. The transition to 85-mm cannon immediately changed the situation, allowing the Soviet tank crews to fight the new German tanks at ranges of more than a kilometer, "Well, when there was a T-34-85, then it was possible to go one on one" (Iron). The powerful 85-mm gun crews allowed the T-34 to fight with his old acquaintances at a distance Pz.IV 1200 - 1300 m example of such a battle on the Sandomierz bridgehead in the summer of 1944, we can find in the memoirs Zheleznova. The first T-34 tanks with 85-mm gun D-5T rolled off the assembly plant Љ112 "Red Sormovo" in January 1944 to begin mass production of T-34-85, this time with 85-mm gun ZIS-S-53, was laid in March 1944, when the first tanks of a new type have been built on the flagship Soviet tank of times of war, Љ183 factory in Nizhny Tagil.
The only inconvenience that caused the introduction into service 85-mm gun was the need to watch closely to long barrel does not touch the ground over the potholes of the road or the battlefield, "the T-34-85 - a long barrel. Metra four or more. Slightest ditch , short barreled ground and pecked a little lacking. shot, the barrel as the anchor breaks, does not tear it, and so pushes. As a lily of the valley, rose disclosed in different directions. Usually 3 - 4, and that's because they are wrapped, and all trunk out of order "(Rodkin). Full length of the barrel 85-mm tank gun mod. 1944 was more than four meters, 4645 mm. The emergence of 85-mm guns and unexpected way affected the defeat of the tank, he ceased to explode with the breakdown of the tower: "The property is a T-34-85, they [gun shots] do not detonate, explode them one by one, and completely not. Old T-34 -76 there if one shell exploded, then detonates all combat pack. shells exploding "(Rodkin). This is to some extent increased the chances of the crew members, "Thirty" for survival and photos and newsreels of the war faded picture, sometimes flickering on the frame 1941 - 43 years. - T-34 lying next to a tank or upside down after falling back on a tank turret.
If the German tanks were the most dangerous enemy "tridchatchetverok" then do the T-34 was an effective means of destruction weapons and manpower that hampers their infantry. Most of the tankers, the memories of which are given in the book, have to their credit, at best, a few armored vehicles of the enemy, but the number of people shot out of a cannon and machine gun enemy infantry in the hundreds of people. Ammunition of the T-34 consisted mainly of high-explosive shells. Regular ammunition "tridchatchetverki" with the tower-"nut" in 1942 - 44 years. consisted of 100 shots, including 75 high-explosive and armor-25 (with the advent of sub-caliber ammunition from the 25 units were equipped with 4 pieces piercing shells). Regular ammunition of the T-34-85 provided 36 high-explosive rounds, 14 armor-piercing and 5. The balance between armor-piercing and high-explosive shells in many ways reflects the conditions in which fought "Thirty" during the attack. Under heavy artillery fire tankers in most cases have little time for the firing range and shot on the run and short stops, relying on the masses of the enemy shots or shoot a few rounds.
