Is there a 375 Weatherby? I know there's a 378 which is same case as the 460 necked down. Much larger that 375 H&H. I told a story on a thread here awhile back . A man at the range had a 460, 378, 340 and 300 Weatherby rifles. I was shooting my 7mm Rem Mag. I had never shot anything bigger than 30.06/7mag. I was about 18 yrs old. My best friend was with me. I was watching the guy shoot his Weatherby's and thinking holy cr@p ! He asked if we wanted to shoot them. Heck ya ! I shot 460 first. I thought it gave me a concussion. Shot 378 next. Recoil felt about same to me.
The 340 felt mild after those two. The 300 no big. My friend started off with 300 first.
Then 340. I saw his eyes get big after that shot. He shot the 378 and said screw that. He didn't shoot the 460.
I told him you should of shot the 460 first. Razzed him on that for a few years after
