There is a good discussion there, but most important notes on Page 3
From what I know (I haven't kept up for over a year and a half)
We have an old Russian round, and an Israeli round(s) that slightly outperforms it. These would be expected to have about 500 mm penetration LOS, so not that impressive. Enough for Pak T-55/Al-Zarrar, but nowhere near what is needed on T-80 front. These rounds are NOT in production.
After research work, DRDO came up with the indigenous
http://ofbindia.gov.in/products/data/ammunition/lc/37.htm - the MK.1 round and a few years later,
http://www.ofbindia.gov.in/products/data/ammunition/lc/26.htm - I don't know if this is the MK.2, but the other round in production
It was reported MK.2 passed trials and entered service, but idk if it got redesignated or they kept it secret on purpose.
We also bought the 3BM42 round from Russia (not latest, but pretty close to 3BM48, the best) is being bought, and these have penetration 600 LOS, so I would say they are still not enough to penetrate a Pakistani T-80UD full on (You would need the M829A2+/DM53 for this) but sufficient to penetrate from weakspots on the front/side without a problem.

3BM42 described in that page at the end. (3rd from bottom, it is a common round apparently)
