your 5r is an 11.25 twist. if your gun doesnt shoot varget its probably broken. that being said it doesnt provide the best velocity. if speed is your need look at rl15, imr 4064, cfe, mr2000 and imr 8208 all yield better velocities and some meter better than others. go to hodgdons website and see what your options are in their lineup. promise you will find something that shoots lights out in your 5r
