Just some humor for you forum members.
I tried a Bushnell TRS red dot on one of my 500 Mags. Bushnell said it can handle 12ga 3" Magnums.
I shot 4 medium heavy rounds and totally destroyed the scope. Objective lens was 45 degrees from normal, like a bloated fish. Don
I've read that the 3.5" 460/500s destroy just about all optics.
I recently called Trijicon and Leupold and was advised that the RMR and DPP would be covered under warranty if the recoil damaged them on any gun.
They said to try them on my short barreled 458WinMag as well.
I milled a temporary mount from aluminum before that,
and before buying parallels, and both were okay with
medium stout loads.
I still have 16 of the 200gr FTX Hornadys left.
The first two broke the 3.5"s trigger and cylinder stop,
some years ago. Smith got it back to us right quick.
I pulled two to compare the powder to H110
But for the real blasters, I'll try the old Leupold DPP first.
I trust Leupold's warranty.
The mount in pic will be replaced by a slightly longer
three screw mount.
Just for some range fun on the 3.5" as it's carried with irons.
Will most often have the red dots on the 8"+ 460 so normal
people can try the gun/stocks.
The 2.5-8x32mm scope for those experienced shooters
with eye care insurance.

Keep 50-100 TrailBoss loads on hand in the range bag.
