Many years ago, I regularly brought home the bacon using a Buckmark Micro with a custom flush comp and red dot on bowling pins. Never a hiccup with Winchester Super-X. Now, after many thousands of rounds, it will not cycle cheap stuff reliably. Most likely due to cheap ammo being next to worthless recently.
Have a standard model that I use for squirrels and plinking with iron sights. Very accurate. Wouldn't hesitate to buy another.
