A firing range isn't just useful for practicing shot placement, it's also for getting used to how the gun operates. We lose that when the weapons magically reload at ranges. I want to see what the chambering looks like, how long it lasts, and build an instinct for how long until I need to reload with a particular gun.
In the stream today Jaxy confirmed that the skeet/trap range works the same as the one on Hirsch, going so far as to point out that it means all shotguns will operate like a semi auto. That's a downside to me, and takes away options from the community-generated competitions the devs seem keen to encourage. There's no point in players mixing it up with the style of shotgun they're competing with if they all work the same on the range.
At the very least please add another button at the ranges that toggles it.
