I would have thought that anyone that was even in bear country at a minimum, would make sure their guns functioned flawlessy from the mag to the chamber as fast as you can go.
I would not think IF he had a jam, that it woudl be breaking news, make sure your gun and ammo work..
The last time I loaded for a friend to Africa, I cycled every round of 416 through his gun as fast as I could run the bolt.... and sized the brass such that it was an easy fit but not sloppy, in the chamber.
He had NO intnetion of anything more dangerous than an Eland/Kudu... but you never know.
