I’ve been using the Whitetail 129 IL load in my Creed on three big blacktails to date and think very highly of the ammo.
It shoots about as well as I can, out of my Kimber Hunter - hence, I’ve not reloaded for it yet.
I’ve killed two full grown cow elk with that Hornaday 129, as well. Out of a .260 Rem, one shot apiece.
