The Ishapore 2A and 2A1 were manufactured as 7.62x51mm from the get go. They were not converted 303s.

What you will find is the headspacing is 7.62 NATO, so if you run 308 gauges into it, the rifle will likely fail the NO GO check. In other words, the bolt will close on the NO GO gauge. This DOES NOT necessarily mean the rifle is unsafe to fire. It means there is a little extra room for the NATO cartridge.

Here's a bit of light reading about 308 vs 7.62 NATO.
