Actually in battle the recoil is a non issue. The extra weight of the rounds is. All of the extra size and weight for the grunt to carry would have more impact.

As an aside, when has high command ever had their pulse on the needs of the enlisted?

Praise the Lord for full Salvation
Christ Still lives upon the throne
And I know the blood still cleansess
Deeper than the sin has gone
