First big bore rifle I ever fired was a 45-70 Trapdoor Springfield made in the 1870s. Yeah, it kicked all right, but I did fire 5 rounds through it. I was 14.
I forgot to add that I fired a friend’s AR 15 and the recoil wasn’t much more than that of my .22 mag rifle.
Same here. Cut my teeth on a 45-70 trapdoor 1873 Springfield. My brother still has it. We get it out every couple of years.
