Father used a 351 Win self-loader with 180gr loads for many years which accounted for many a deer over MN, Wi and Mi tight close shooting northwoods which is one of the things that attracted me to the Legend, Older brother inherited Dads 351 which ammo is hard to find now days. Brother took his largest Wi whitetail with a 350 Legend which I built for him dropped in woods road it was crossing when shot using 170gr load.
I have taken multiple bucks as well as does in both Mn and Wi with my own Legend with 170gr loads.
My only guess is that the deer do not know that 170gr is to light for caliber.
not something I would be tempted to try on moose.
the Buckhammer does look interesting just because who doesn't like trying something new oh yeah and a 6.5
