In the re- loading manuals I consult to work up a load there is listed the m.o.a.l., followed by the vel and pressures the load will preduce using x amount of powder and bullet type and weight. Are these figures based on the moal? Put simply, I realize there are many variables, but is the published data based on the bullet being seated at the MOAL? If not, and the bullet was seated at the customary length for the firearm being discussed, the data would be altered. Any thoughts on this appreciated. dang
