How many rounds have you put through the .375 while it wears the Leupold QD mounts? I had them on a .338 once and it would slowly tighten up as the round count increased until you could barely remove it with your fingers. Take it apart, remount and start over again. Really annoying and that was the last time I ever used one (about 20 years ago).
I have not had that problem but it doesnt get a lot of rounds put through it either ( better calibers to plink with
