The modern battering ram is also much smaller than what you've made. so you could still combine them, with the front moving away or opening to hose targets down with rifle rounds And if you want more of the mass to be static, just "downgrade" to 5.56 which means you can pack more rounds in the same space, you can have a higher rate of fire, and the gun is smaller.
