Hopefully it would hang together on the 458 WM and survive a 500 A Square loading(when I could have such a gun built).With my old eyes I use open sights but prefer a scope if possible.At 2x it sounds like fun on a heavy recoiling rifle with the possibility of at least 5" of eye relief.
Maybe it would even work with claw mounts on a Double!!
