I borrowed one of Karl Stumpfe's Mausers in 8x68S in Namibia to try a 8x68S out. His rifles were above par and excellent.

Some of the client loaner rifles I have seen in various outfitters camps have been horrible.

So if loaning a rifle, make sure you know what you will be getting.

Also on another safari a rifle was supposed to be available for me, I did bring one of my own. No one told the PH so the other rifle was NOT available. It wasn't needed but could have been a huge problem.

So beware if you plan to use a client loaner rifle and be forewarned and prepared.
