I’m not sure I have that level of coordination (to work a pump that fast.) I have a Remington 870 Wingmaster too, and, I dunno. I think I’d have to practice with thousands of rounds to hit even 1/2 the firing rate of a semi-skilled auto user. It sounds like you are essentially saying pump and re-aim in the same motion, and I’ve never been able to make that work. But, again, you’ve probably outshot me by a factor of 1000! ;-)
I do tend to agree about field reliability — there’s just more that can go wrong with an auto, but... this gun isn’t going into the field.
Probably, I should see if I can try out an auto at a range...
Duck hunters get plenty fast with a pump. Muscle memory is important. That’s why I chose a Winchester 1300 Defender for home use. It happens that I learned to duck hunt with a Winchester pump, and the controls are second nature. And I much prefer the safety in front of the trigger to behind it, as in the 870.
