I have a Classic Big 5 with 2 barrel sets in 500/416 and 9.3x74R. Both sets have the High Vis sights. Ugly, but my poor near vision can actually see/use them.

The 9.3 has a Kahles 1.1-4 on it. The 500/416 is at Krieghoff USA as I type this getting set up for a Schmidt & Bender 1.1-4 on their QD mounts. I had not planned on scoping it, but my conversation with my PH at SCI said the time of year we are hunting in Mozambique could require longer shots if the tall grasses are down due to dry conditions. Thought I'd hedge my bet and have the easily removable scope as an option.

My other is a Krieghoff Classic in .30-06. Not the non-flanged caliber I would have chosen, however the price was VERY right and it is a left handed rifle. This one wears a Kahles 1.5-6 on it. Last June I used this rifle with the 1.1-4 Kahles now on the 9.3 barrels to take a white springbuck at 210 meters (laser verified).
