Oh yes. I recall reading of calibers up into the 70cal. Many of the old rifles were bored bigger and bigger at the black powder coroded the bores. They would just ream them bigger and rerifle them. Of course I am not quite that old. I mean I don't remember those days. I shot a lot of deer with my old 22 long rifle. There were no deer seasons where I grew up when I was a kid. Anything good to eat was on the menu. There were deer around mut only in certain areas and not enough to have a season. People just hunted when thet needed meat.
