Remember, 77mm NOT THE SAME as 17pdr field AT gun:

The A34 (the General Staff specification), later named Comet, the tank designers opted to correct some of the Cromwell's flaws (the track shedding and broken suspension problems) and enhance the Cromwell's main strengths, low height and high speed. Originally, it had been expected that the tank would use a new gun from Vickers: the "High Velocity 75mm". However, as designed, the gun would not fit into the turret size available. So the gun was changed to a different gun, the "77mm HV". This gun used the same calibre (76.2 mm) projectile as the 17-pounder but the shell casing was from the older QF 3 inch 20 cwt anti-aircraft gun loaded to higher pressures. The resulting round was completely different from 17-pounder ammunition. It had a lower muzzle velocity than the 17-pounder but the ammunition was much more compact and more easily stored and handled within the tank. This made it possible to mount the gun on a smaller turret ring – the Challenger turret had been so large to allow space for two loaders[note 2] – without making the hull wider. Several other improvements were made: armour protection was increased, the hull and turret were welded[3] with a cast gun mantlet, ammunition was stored in armoured bins, the suspension was strengthened, return rollers were added and the turret was electrically traversed (a design feature taken from the Churchill tank), with a generator powered by the main engine rather than the hydraulic system of the Cromwell.
