My first .458 was a #1 Tropical I traded a pistol for. Only scope I had on hand was a solid performing Bushnell Sportview 4x. I thought "why not?". That thing held up and dialed in like a Zeiss! Maybe the rifle was heavy enough ( like a truck axle) not to bother it, but it was a surprise. Now, I never took it out in the rain/snow. It may have fogged up. I had a Tasco World Class 2.5x10 on a 30.06 that held zero, dialed in real sweet, yet fogged up on its first hunt. You "still" get what you pay for, ha.
I forgot to add that the Weaver 1x3 worked swell on every .458, 416 Rigby, 416 Remington, 416 Taylor I tried them on!
