First, welcome to the site and thank you for your service.
I am not a competitive shooter, nor have I had the pleasure of much varmint hunting. However, my experience from the bench and just "goofing" around is that the rate of fire you describe is fine with either barrel contour, in most cases. However, barrels are like people. They each have a personality of their own and some are more sensitive to heat than others. You may find it needs a couple minutes between shots and then several minutes to cool off after 5-6 rounds. Weather plays a role as well. Powder and load choice also plays a role as well as loading practices. (Chamberring a round in a hot barrel and letting it sit there a few minutes before firing will have a different affect than leaving the chamber open and loading a round immediately before firing.)
