325 WLN vs 300 LFN vs 250 LFN .45 cal?

[HHI 812]

Veral,

Which, in a 45 caliber, would deliver the best punch for large game like moose and bear? A 325 WLN GC @ 900 fps vs a 300 LFN GC @ 950 fps or a 250 LFN GC @ 1100? Where would you draw the line in velocity being too slow or where there is enough velocity for better punch? Was playing with your DV formula with different meplats, but when would a WFN be better than a LFN? Or when is higher velocity be preferred over say a heavier bullet? In other words, can have the DV with equal values, but have one being a LFN, another a WFN, by just playing with the velocities. My limitations is I have a short barrel, small frame 45 Colt. I also noticed there is a 460 Rowland for a 1911, shooting a 250 grain LFN bullet at 1350 fps. Would this be superior to any of my 45 Colt loads out of my small revolver? Again, which is preferred? Fast light bullet LFN vs big heavy, big meplat slow WLN or in between WFN medium speed? Which hits best?

Thanks,

Dennis

Thanks EdK! That graph really shows it all. Seems like meplat is the big factor. So seems like that WLN even at 900 fps is superior to high velocity.
Thanks again EdK!

I'm glad you appreciate the graph. I came up with a system for quickly doing this for all of my LBT mold applications. This is certainly a case where a picture is worth 1000 words. I'm not trying to address your questions though and defer to Veral on those - I just know the graphs prove helpful at times when we're tossing around various scenarios in our heads so added one particular to your application.

So Veral, how does bullet weight fit into this DV equation?

[Veral]

  Weight doesn't figger at all in the DV formula.   Splash of displaced tissue is the same regardless of weight as long as meplat and velocity are the same.   However, light bullets do lose speed faster in flight and during penetration than does a heavyweight, but it isn't a concern for most hunters if they choose any mid to heavy weight bullet from the LBT lineup.

  Unlike bullets which expand and create very large wounds, with extremely high velocity loss during penetration, wide meplats do their work very efficiently.  In an experiment.  Using a 44 caliber WFN and LFN as comparisons, both 300 grains.  The LFN  penetrated  52 inches in wet newprint while the WFN penetrated 50 inches.  This with  the WFN chewing a "wound channel' way over twice as large in diameter.   That much penetration in wet newprint would equal about two adult moose lengths.  Stem to stern through the body in other words.
 
  If deep penetration is a concern when ordering an LBT mold, contact me before ordering and I'll help you select the right mold for your needs.
