Unless the noses of the 140's are really weird, you should be able to work up a load that will function the Garand just fine. Use "faster" powder 147g load data as a starting point. (IMR4895 and it's brothers). Even so, start low and work up.
Using the data specifically published for the Garand would be a better bet, since proper loading for it is more constrained than modern bolt guns.
Two critical items to avoid slamfires (see threads elsewhere here) are primer seating and case resizing to proper dimensions. Using a cartridge headspace gage to check the resized cases (and even the loaded cartridges) is cheap insurance against such unpleasantness.
