Thread: The Maths of Recoil

I've been contemplating lightweight rifles. The downside being increased felt recoil. So the question is do efficient cartridges that achieve good velocity with smaller powder charges have less measured recoil than a cartridge burning more powder to achieve the same velocity ?
Newtons third law does not consider the rocket effect of burning gases or the weight of the gasses (propellant) that are also accelerated.
