First round was battle carried, sabot. Then I attempt to load a heat, driver is backing down into the defilade, brakes a little too hard, got the round in far enough to raise the breech, but not fully. Have to lower the breech manually, pull the round out a bit, then reattempt to load it. Third round is heat, loaded with more ease.
Heat rounds weigh 55 pounds and are about 4 feet long. They're a tad bit ungainly to move around in the tank.
