WFN vs LFN vs WLN ?
« on: August 23, 2004, 04:39:03 PM »
I have read both the catalog and the "Jacketed Performance with Cast Bullets" book but still have a question concerning nose profiles of revolver bullets...

    WFN has a larger meplat than LFN = understood
    WFN has larger wound channel/LFN has greater penetration = understood (for a given caliber & weight configuration)
    Deducing that WFN results in more weight forward of the crimp groove(for a given caliber & weight configuration) thus offers more case capacity than LFN[/list:u]

    How then does the WLN fit in? Is the meplat like the WFN or LFN (or neither)?

    The end result will be to have selected the right bullet for a 454 Casull & heavy 45 colt loads. I'm presently thinking the widest nose profile in the vicinity of 325gr as the game is deer/caribou/mouse not big bears, African game and so on. Except for the possible moose the game to be encountered is not overly large and won't likely be biting back so quick kills are more important than ultimate penetration. Besides I don't really envision a 325WFN @ 1200-1600fps having much trouble penetrating anything in the lower 48...

    Thanks, Ed

The Casull 454 will only handle a .4 nose length, and for it the WFN will give maximum powder room, which is only needed if you want screaming speeds, of 1700 fps+ with a 340 gr.  A 325 gr will work fine for anything you mentioned when started at speeds down to 1200 fps, so powder room isn't a factor in getting very good working loads.

The WLN has the same meplat as the WFN but allows a longer nose length for guns with cylinders which permit noses of .450 (Ruger Blackhawks and S&W's) or .500 nose for Redhawks Anacondas,etc.

The LFN is suited to any nose length from 400 to well over .500, and punches a somewhat smaller wound than with WLN or WFN, assuming similar impact speeds and caliber.

You will  not have penetration problems with any of them on game up to moose and large bears.
