That's a fair self-assessment
@Fastrig
What I would say in counterpoint is that A.) The hunter is ultimately accountable for his actions and his own safety. B.) That 90%+ of people do not know how to use a straight-pull R8, nor a double rifle with minimum proficiency.
It is a very rare thing that someone uses an R8 and keeps the rifle to their cheek while pulling the bolt back to their face...it takes faith and memory that the bolt will stop before it hits your eye. It also takes proficiency to load, shoot, and immediately reload a double rifle. Both proficiencies can be built over time. If you have a heritage of using double barrel shotguns with double triggers in your past, the double rifle muscle memory is largely there before you purchase your first one. Same if you've used straight-pull rifles like Mannlicher Steyrs and Schmidt-Rubins and Ross rifles previously.
I do not think your preferences are negligent or flawed at all. I have a different confidence, aesthetic, and preference but your way isn't worse, its just different. Anyone that says either way is unsafe is a fool. In both cases, proficiency with one's weapon is the ultimate deciding factor.
On that note, everyone go play with their guns and make sure you can operate them flawlessly.
