Looking to see if some can share some real experience with hunting using 45-70 cast with black powder for large game... I read where some say that a bullet needs 1200ft/lbs of engergy to humanely take an elk... I plan on using either a 513 gr RN or a 396gr FN, most likely going with the heavier bullet...MY current load has a MV of 1139FPS with the 513Gr...which calculates to a max range of 150 yds using the "guide" of 1200 ft.lbs and the 396gr wouldn't make it to 100 yards.... this does not seem realistic... I know the trajectories are rainbow like, that is a given, but once a large heavy object gets moving, I think it would get the job done. ballistic calculator shows that the 513 gr. would have 1149ft/lbs @ 200yds, 1093ft/lbs @ 250yds and 1043ft/lbs @ 300 yds.
I only want to be able to shoot an elk within my proven range for accuracy...hopefully out to 300 yds..... not prove how far I can kill the animal. I certainly don't want to lose one to either poor shot placement or inadequate ammunition.
Can anyone share their personal experiences? Greatly appreciated,
