With the XM25, ATK has increased the size of the grenades from 20mm to 25mm for increased lethality

According to the Fire, Fusion, and Steel weapon generation system, 20mm is really the minimum caliber feasable for explosive munitions - and that only at the higher tech levels, or with direct hits. 25mm is an excellent compromise between small grenade size and munitions effectiveness against soft and lightly armored targets. Funny how a game system appears to have gotten it right.
