I have owned two Remington XR-100 in 204 (1st one was Stolen) The 1st rifle would shoot the 40 V-Max/39 Sierra's so close to that you had to measure the groups to tell the difference.
The one I presently own shoots as well as the Original rifle with the 39 Sierra's BUT the 40 V-Max groups are almost DOUBLE the size
Good Luck
Jim
