Hey Moose3!
The KD at Searsboro is being held at
https://www.bigspringsrange.com/. We will be using their 500 yd bay, which will have a moving firing line so that targets can remain at the berm. That may mean shooters may want to forgo a shooting mat to have one less item to move from firing line to firing line. And that's not a bad idea to get used to shooting without a mat. Firing lines are on turf.
There are three 25yd Appleseeds in Iowa before the KD -- Clinton, Birmingham, and Dubuque. Perhaps consider attending one of those to practice up if it has been a while on the AS firing line.
The KD will feel familiar in some ways to a 25Yd AS, but shooting full distance (100, 200, 300 and 400 yds) is a different, but very worthwhile, ball game. I hope you decide to join us for the KD! They are incredible! You will learn a ton about yourself and your rifle at full distance.
