50 might be fine. I don't doubt that the Merkel would, if I let it. Possibly the Greener too, though I haven't patterned that gun that far. But I just don't do it. Lots of birds will end up dead, but some won't. That can happen at any distance, but more so the further out it is, of course.

I like a few more pellets so I generally opt for 5s.

One things is certain, the pellets will never know whether they were launched with black or smokeless, so it powder isn't the issue.
