Here is a little info on WFN WLN and LFN
WFN and WLN have the same meplat for a given caliber and weight
LFN have a smaller meplat than the WFN and WLN
LFN will be more accurate and have less drop than a WFN or WLN over long distance due to the smaller meplat (LFNs are a good rifle bullet)
WLN have a longer nose and smaller bearing area than a WFN
generally a WFN will be the more accurate than a WLN out of a revolver that is off alignment between the cylinder and barrel due to the extra bearing area.
WLN will allow for more powder room than a WFN, but will also give a longer OAL
WLN will allow for easier seating due to the nose starts to taper right after the crimp grove. The WFN nose starts to taper around 1/3-1/2 up the nose after the crimp grove an therefor the bullet can be hard to seat sometimes.
