Try to find euro review sites / hunting forums. Some of those stalking oriented guys (e.g. in Germany) are going to RDS on their hunting rifles. I gather, the ones they sell for this are rated to pretty stout stuff as I have seen them mounted to express rifles for dangerous game also.
One I have even owned is the Z-point. It is a civilian, hunting-oriented version of a Hensoldt-branded Bundeswehr-issued sight, with picatinny, weaver and some specialist mounting systems like for the Sauer 303 or Blaser F3. Here's one (not mine, promo photo) on an R 93 used in a driven hunt:

Another Zeiss dot I don't know about till now (the Victory Compact Point) mounted to a 9.3x62 rifle of some sort

Aimpoint actually sponsors some hunters like the almost trick shot boar hunter Franz-Albrecht Öttingen-Spielberg, seen here with his Sauer 202 also on a driven hunt:

I suspect they, therefore, have high recoil specs on their stuff for this use case. Just need to find the right guys to talk to, since they don't have much business like that in the US.
