You have it quite right, with the WFN the quickest game killer. The WFN cannot be seated out as far as the LFN, thus, less powder room and velocity potential. Some say it isn't as accurate as the LFN, but I've had many reports of one inch groups at 100 yards using the 300 gr 44 and 325 gr 45, and, I've accuracy tested all my bullets at 450 yards. At that range chest shots on small deer are easy once you get the elevation.
With the LFN seated out, and in the heavier weights, power and accuracy cannot be beat by any bullet ever made. I'm speaking here of 41 through 45 calibers. Many order WFN's for the 475 and 500's, but I prefer the LFN for them as the nose flat is very large, so it at least matches the smaller caliber WFN performance on game. For 357 and smaller, stick with the FN, which is the WFN profile, except for iron targets, where a heavy LFN will perform best.
