Lots of hunters do that. Unless you wrap the whole roll of tape around your muzzle it won't have any impact.
But it will keep dirt, rain, and twigs from getting into your barrel or chamber.
I was black bear hunting with my buddy once and when he went to chamber a cartridge he couldn't close the bolt. We'd been busting through some alders. A small piece of twig had dropped down the muzzle and was lodged in the chamber.
I always tape. When I chamber my rounds, the bolt always closes.
