Will it handle recoil from 416 Rigby heavy recoiling rifles?

I have used them on .375 H&Hs and smaller calibers. I have used the 1.8-5.5X Conquest on the .458 AR after checking w Zeiss (who said it could take it).

No problems at all.

I'd think the 9x isn't necessary on the Rigby ... but each to his own

You will not have any problems with recoil. It can and should hold up no problems.

Mounted properly, it will serve you well.

As mentioned, properly mounted, no problem. I know a couple of people that have them mounted on 378 Wby that have had zero problems (braked and non braked).

Ken....

Thanks gentlemen. That is what I needed to hear.
I originally used the 416 as an example, but only plan to put one on a 9.3x74 and a .338, and possibly a 375 H&H.

Begno,

I have the 3-9x40MC on a .338 WinMag, a 9,3x62, and two .375 H&Hs. Wonderful scopes of a decent objective size. Love'm!
