Can anyone tell me the ft. lbs. of energy at the muzzle, from the newish Winch. Supreme 30gr. cartridge? It isn't mentioned on the Winchester website.

30gr X 2250 x 2250 x .000002215 = Energy

Or, 336 ft/lbs. of muzzle energy. Being a 22 caliber, 30 grain it will bleed velocity and energy quickly.~AMMOe

Thanks Ammo!

The #'s are impressive on this cartridge. I'm surprised we haven't heard much about it, from the field.

I intend to use the Hornady 30gr Vmax on ground squirrel this year. I works quite well out to 100 yards a the range, so I have faith that it will prove to be a small critter gitter.
