Probably would've already went there if it was a 20WSM slingin 30-ish grain pills.
It came out 50 years ago. It's called the 5mm Rem Rim Mag and it kicks both the .22 Mag and the HMR to the curb. Shame that Remingjunk never put it in a rifle that did it any justice OR supported the ammo for more than 20 years.
Be that as it may...………… I still own a pair of them and they DO rule the rimfire roost on killing. Best is 280 lasered yards (lasered it AFTER the shot) on a small groundhog. I'm certain the rifle can do considerably better, given an opportunity.
