I was wondering the same thing...I wonder how long it's been since .30-30 ammo has been headstamped .30 WCF?
That would make a good T-shirt slogan.But its better to stick to proper ammo
.303 fires a .311 or .312 bullet so I suspect it was nothing to write home about.

Low pressure round with a small bullet for the bore
Maybe not even an issue with gas blowback, because of the rim, especially if it was a tight fit headspace wise.
I tried to shoot a 30-30 factory cartridge out of a No4 many decades back but the bolt wouldn't close on the rim because it was to thick.
2 or 3 years ago I was out scouting for goats with a buddy who won a limited entry hunt. I stopped at random and looked down to see a single piece of brass perched on a rock. It was of calibre 33 WCF, which looking it up when I got home has been discontinued since 1940 (https://en.wikipedia.org/wiki/.33_Winchester). I took a picture and put it back for someone else to maybe find in the future (I doubt I could ever find it again if I tried). Take a look at the picture taken from where I found the brass amongst a field of boulders
A .30 bullet through a .303 bore is going to hold lots of pressure to get velocity. It is going to engrave in the rifling. There is going to be some velocity loss because of the split case. I very much doubt that the capability to kill a caribou would be much diminished.
