Having worked in a gunshop for over 34 years, I have owned or still own about everything above mentioned. The 600 350mag has a strange kick that causes bone pain. Sort of like a tuning fork running through your body. But for shear punch a Mossberg 835 with 3.5" 2 1/4oz loads holds the title over 416 Rigbys, 458 Wm and a light weight Ruger No 3 in 45-70 with hot loads. I have not gotten an opportunity to fire a 600 Nitro or 755 Tyrannosaurus nor do I want to just to say I have.
A bowhunter at heart but a gun guy at soul. I'll take craftsmanship, wood and blue steel over plastic and composite any day.
