I use the WLRM in everything. I tried the rest of them, and wasn't happy with the results. The Winchesters gave the most consistant velocities across the chronograph with the magnums and the standard loads. Remingtons gave a 45 fps deviation. Federals gave 25 to 30 fps. CCI's gave the same. Winchesters dropped the deviation to 10 to 15 fps.
