My dear 416 Taylor was built as an northwest Wyoming elk rifle. I guess elk don’t need such a cartridge but don’t tell them. 350 grain Speers at 2550 just dump them, no trailing involved.
Did a lot a bison hunts, 400 grain Hornadys exited always, 350 Speer got six feet of penetration front towards the back. Just a wonderful cartridge. Picking up 7 mag brass and reforming to 416 just warmed my heart and turned a useless object into a real cartridge of great power. After years of the great 458 I wanted a little better trajectory so built the Taylor. Had a wounded bison cow a ways out, held the front sight on hair. 400 grain Hornady soft smacked and she fell on her nose. My old 458 would have to have held above hair.
I sold it recently as I have two more cervical fusions to endure in November. The sale of that rifle has saddened me greatly.
