I thought the record for artillery range was 48KM by ATAGS. Evan kalyani mentioned it in one of his interviews. Is that not the case?
Oh yes, apart from chamber it depends on type of charge and shell
There is a type of shell M1a4 ERFB : BB
Which is extended range full bore base bleed
@Kuldeepm952. Bhai apne HEER shell kaha tha , wo shell utna use me nai hai
Heer ka matalb high explosive extended range hai .
The shell erfb bb is the most common shell .
In erfb bb and erfb bt shell, there is oval outward surface at the base on three sides absent in HEER type.
Army usko utna use bhi nai karti hai
This is a erfb bt shell , the bt is boat tail shell both bb and bt are similar in design and outward appearance .
I have closely seen all pics of atags trials , only erfb bb shell and erfb bt shell are used for trials.
Heer shell are not even made any more
In all exercises its this erfb shell .
Its a licensed made from a denel south Africa ammunition of same name.
