People who have shot Elk with both cartridges see any difference in killing power?
Thanks,
You are not likely to see much difference at close ranges. With top loads for both, the .300WM adds 200-250 yards to what the .308 does in terms of retained velocity and energy.
Using Barnes data, since I like TTSX and LRX bullets and based on 7000 ft altitude:
.308 W, 168g TTSX, 2877fps MV, ..470 B.C
.308 W, 175g LRX, 2728fps MV, ..508 B.C
.300 WM, 175g LRX, 3120fps MV, ..508 B.C
2000 fps retained velocity
----------------------------------
560 yds = .308 W / 168g TTSX
615 yds = .308 W / 175g LRX
825 yds = .300WM / 175g LRX
150fpe retained energy
----------------------------------
590 yds = .308 W / 168g TTSX
610 yds = .308 W / 175g LRX
855 yds = .300WM / 175g LRX
I don't care what bullets or cartridges others use, but it is common sense and simple physics that, in terms of retained energy and velocity, the 308 Win will become marginal long before the .300Win follows suit. Whether that will impact a particular situation depends on the situation.
