Why not 10 shots? I don't personally shoot 10 shot groups, but don't see a problem if someone wants to. Besides those 10 shots could have taken an hour or more to shoot, my buddy didn't say.

Barrel was free floated with plenty of room, no chance of it making contact with the stock. The action is bedded to stock with no bedding forward of the recoil lug. Oversized squared recoil lug and barrel nut were used as well.

I seriously doubt 10 shots even if in rapid succession are going to do much damage to the barrel.
