Both of these cartridges are ball busters. The 470 GNR will put the 325 grain XTP out at well over 1600 fps, the 375 grain WFNGC at almost 1500 fps and the 405 WFNGC at almost 1450 fps.

The 501 GNR will put a 390 grain WFNGC at well over 1400 fps and the 425 grain WFNGC at almost 1450 fps.
Both of these cartridges were tested in 10" Encore barrels.
