Without a doubt. And it was probable like shooting a .22 WMR.
I killed everything I shot at back in the’80’s with 6mm Remington .58ga Hornady HPBT@ 3600fps going out a Ruger M77V. out to 400yds.All head shots . Kept meat on the table for a lot of WVa. boys. At the time I lived in the middle of 2,000 acres of West Vaco Pulp&Paper land.
Wistle pigs were fun too. Hit one in the breast one day at about 200 and kicked him in the ait about 8 feet and backwards about 15.
I wish I had my reloading stuff set up. The ammo today @95gr is just not anywhere as good.
