RE: Soviet heavy SP guns
Rifled... it's old age setting in, cuz i knew that. Thanks guys. POS brings up a point that is interesting.

Gun accuracy is roughly linked to its muzzle velocity, best large-calibre Russki SPG in that respect is the ISU-122 and its mate the 'S' model which have AP m/v's of 790 metres per second, which is almost as good as the T-34/85 (800 mps)

Next best are the ISU-152 and SU-152 at 600 mps which is still pretty good.

Worst is the SU-122 (336 mps) with its stubby little gun.
(That's another thing, short guns of all nations are usually low-velocity and can't hit a barn door)
Having fired nothing larger then .45 cal never mind 152mm, I am gonna forage out of my comfort zone and say accuracy has nothing to do with muzzel velocity. At least in rifles, my short barreled 45-70 gov't is extremely accurate even though the bullet is only travelling about 1,300 feet/second. They used this cal. to hunt bison at 1,000 yards and more with iron sights, and at that range a bison is a rather small target. My .338 cal. in a long barrel is also accurate travelling at 2,300 feet per second, I cannot say which one is more accurate.
Would not the same rule apply to these large guns? A high velocity gun would not require as much aiming adjustment at different ranges, but it's nothing that can not be accounted for by the trigger man on a low velocity gun. And as for penetration, bullet weight should out perform bullet speed, all else being equal.
