the big question is why. if you need rounds that fast just use a detachable magazine setup and you instantly have 4 fresh rounds on deck. The rifle I use the most these days is a bat machine action with machined in rail, big honkin nightforce turrets over it, never had any issues with port access and this gun is alot tighter than a standard remington. of if you really need rounds that fast use an ar 15, especially with the fur trapping coyote story, ar 15 them!!
