Implications of a larger chamber capacity is that more powerful charge can be used and the shell can be hurled a longer distance.
For comparison the G6-52 with 23 Litre chamber gives 42km and 55km maximum range with Assegai M2000 ERFB-BB and V-LAP shells using the M90 BMCS, the G6-52L with 25 Litre chamber on the other hand gives an astonishing 50km and 67km maximum range with the M9 ERFB-BB and V-LAP using M64 BMCS.
Similar range increase can be expected with the DRDO ATAGS when compared with a contemporary 23 Litre chamber L52 howitzer, provided the charges are of higher power.
G6-52 figures from here, do give it a read.
