If you compete in a Military Match/ Vintage Match you will have one or two rapid fire stages. The barrel will get hot and the rear sight will bind up and not move. This had to be a problem in WWI. Mind you I am shooting light loads, with full charge loads the recoil will beat up the shooter and the rifle will heat up quickly. I would guess the sight would bind quickly then. If you slowly fire 20 rounds at the range you will not have any issues.
