@Dazzler,
@Damian, @Farhan and others - please don't do the mess in this forum and discuss ammo problems in ammo topic
can we do that?
i have menhtioned this before and do it again, AZ autoloadr (it may look similar so i take it as a reference though my source said it is a vastly modified HIT design superficially similar to AZ type) in Ak has been modified since the tank came into service, it has 29 modifications to fit longer penetrators and other ammunition, then it was modified to fit Kombat ATGM again in 2005-06.
It's greate news for Pak.Army - if Ak can carry on Kombat in autoloader casettes then it can bring in casette projectile circa 730mm long. So it's circa (730-750mm?) max lenght projectile avaible in mod.Ak autoloader casette
Akim was postin about Kombat in autoloaders. Kombat have first part circa 730mm long -so if Ak can get this GLATGM in autoloader casette...then there is no other option - casette is long enought to fin in it circa 730mm long projectile. So we have this problem explained and indeed Ak have longer autoloader casette and we have minimum lenght avaible for that. The maximum lenght for that hull is circa 750mm.
ARDE has been making many rounds not only those mentioned in the pdf. Pakistan got TOT for Type-2 penetrator from China in the 90s, janes has an article on it. Type-2M can penetrate more than 600mm armour at 2000 m, some say between 610-650mm at 2000m. AK-1 autoloader is again modified to fit longer rounds than Type-2M. Naiza-2 is rumoured to be able to penetrate 700mm at 2000 m. If true, this is awesome news for Pak armour
Well -on all avaible photos we can see what we can see -so projectile just slighty longer then 3BM42 (those Chineese APFSDS whit green balistic cap) Those APFSDS projectile have overall lenght circa 630-650mm and penetrator lenght whit circa 600mm (balistic cap + rod + fins) and rod (core) lenght circa 560-580mm. So it's better then 3BM42 and only slighty smaller then Sniviets-1. Penetartor whit that lenght shoud be able to perforate circa 600mm RHA at 2000m and maybe 650mm RHA under 1000m. So it's nice value.
IMHO "safe" value to give is between 600-650mm RHA at 2000m and circa 650mm RHA under 1000m.
shell velocity plays a big part in penetration, the one we know of, usual POF APFSDS has 1760m/s at 2000 m. New rounds may be faster
Projectile velocity is less importnat - 1555m/s muzzle M829A3 have the same MJ for penetrator (rod) as shorter but faster DM53 from L-55 gun. But M829A3 is longer (circa 20% more) and haevier. In fact they are many factors - we can have shorter but faster APFSDS, or longer whit composite sabot but mucht slower (M829A3) and they are other solutions. MBT gun ammos is very complicated thema.
even Type-2M can pretty much make a mess of any MBT in sub-continent.

well even if the new round penetration power stand at 600mm of rha at 2km.it can still disable any tank in south asia
Well circa 600mm at 2000m (maybe more) and 650mm RHA under 1000m is big value. In Asia without any doubt only 3 tanks have strong enought frontal armour:
1. Australian M1A1SA
2. Improved Singapour Leo-2A4
3. South Korean K2.
And propably it's all. Not even mentioned that 600mm RHA is enought to kill any tank from sides -so it's tactical problem.
