I predict you won't shoot much skeet with Polywad spreader loads.
Not that it's not a great product, it is.
It's also a standard velocity 7/8 oz. load and your gun weighs less than six pounds. All I can say is, 'ouch'.
In the field, it's no matter... at skeet it equals flinch.
Likewise, the $14/box problem. Not unreasonable for custom hunting ammo, a tad spendy for skeet loads.
Since you stated 'mostly skeet', have it skeet choked. Suggest .003 both barrels. I'd load my own 3/4 oz skeet loads for it, and switch to plated and/or buffered loads for the field situations that require an effective pattern at a bit longer range.
No gun does everything...
