M900 105mm APFSDS-T

[DRG]

Perhaps someone could clear this up

http://www.globalsecurity.org/milita...tions/m900.htm

states

This cartridge is compatible with the US M-1, M-60, and M-48 series tanks emplying the 105mm M-68 cannon.

then 5 paragraphs later states....

The M900 is authorized for use in M1 tanks only. Firing the M900 from any other 105mm tank system may result in failure of the gun mount. Firing in unauthorized gun mounts will result in failure of the recoil mechanism hydraulic seals

anybody have any non contradictory info about that and if any other nation uses this round ??
