I have never fired anything of that size.
The highest I ever fired was 30-06. I can deal with that one, definitely packs a punch though.
My step dad had the 300 win mag, he was going to hunt bear in Alaska with this, and he was trying to set his scope one day up on the farm in South Carolina.
I was standing near him when he fired it, probably about 6-8 feet away, he was in prone position. That thing knocked me off my feet and basically sounded like dynamite going off right next to me.
He just picked up the gun, put it back in its sleeve and put it away. I’m not sure that he ever fired it again.
Oh ya! The Win mag and 7mm Remington Mag have about the same ballistics, except the 300 win mag has larger bullets. Very good rifle for Alaska.
Here is the Lahti, and you wouldnt believe how many of these that are out there. Its a anti tank gun.
