My pick for an underrated cartridge is the 284 winchester, basically 280 rem performance in a short action. Its too bad Winchester didn't chamber it in a bolt action rifle from the get go, instead they brought to market in the M88 lever rifle, so it never really caught on. Light weight rifle builders realized the benefit of the 284win, Nula chambered it and it was the most popular cartridge for them. Precision shooters also noticed the potential of the cartridge and many rifles were chambered for it and its little brother the 6.5-284. Anyway I'm surprised nobody has mentioned it.
It was the parent case for 450 bushmaster and Rem 30ar, which are even more underrated
