well I have 2 boxes of Nosler Partion 180 gr .308 leftover from my 30-06 that I bought to load up for a moose hunt in BC 15 years ago where I literally dropped a 1200# bull in his tracks with them. Think I'll load some up in my 300WSM over a stout powder charge to test for accuracy at 3000fps.
As shots will be under 200 yds I may take my 45-70 with 405 gr bullets along zipping along at 1900fps just for the fun of it.
The biggest animal in weight I plan to hunt is a zebra and I can't imagine one going too far with either of these calibers bullets busting thru his shoulders.
