Answer:
As both the bullets are identical and are fired with the same force. So, to reduce recall velocity, we use, heavy rifle so that its heavy mass compensate the large momentum. But for light rifle, recoil velocity will be large due to small mass thus light rifle will hurt more to the shoulder.

Answer:
The two identical bullets recoil with the same force, but the lighter one will accelerate faster than the heavier one.We can use Newton's third law to explain better.The lighter rifle hurts more than a heavier rifle as the acceleration is higher.
