Frankly I don't get the point of your objection in this case in the light of what I've explained above.
When replying before, I did not see whether a production partner was involved or not, Munition India in this case. Although their job is likely handling the explosives part during making the shell, or if they use an empty shell it still needs the gunpowder (IIT prof or student won't handle that without explosives handling license, neither would the army personnel for making the shell).
So until the tech is proven, no production or even limited induction can happen. 50-100 shells limited trial production is not same as induction, those are used in range firing. Army procurement is like a large initial volume order then about 25-50% of that each year depending on consumable. Now before production happens, MIL need clearance certificate issued by both CEMILAC that is jointly submitted by army & IIT along with test certificates and perhaps the AHSP handover can happen sometimes later.
So its not the critical part I meant, rather the process thru which they have to get thru for just making the product available for production. Since a critical product, it will also need ageing testing for shelf life determination, handling, storage formula development, all of document related to this to be signed by respective army officer in charge. These things take time, at least 18-36 months to get ready for trial production at MIL.
Best part is due to army involvement, they won't have to rely on schedule issue with third party inspection at every stage (which delays every single step from 300-60days , from material procurement to PDI)
example: in below that ATR report cited, it is usually available many months after flight test, data analysis, verification and amendment done to the report which was in 2020. Currently used in a production lot yet to be placed and its 2026.
