I was the founder, co-owner (with Lee Fischer), and operator of the Iowa 1000 Yard Benchrest club near Pella, Iowa. We had a covered firing line with 22 steel/concrete benches and a terrific staff - we have shot registered IBS 1000 yard matches on a regular basis at our club from 2003 - 2010.
We were affiliated with the International Benchrest Shooters (IBS) and the gun rules for the Light Gun and Heavy Gun Classes, and rules of competition, are available on the IBS website - www.international-benchrest.com.
We also had a Varmint/Factory rifle class for accurized factory rifles
NOTE: Due to the unexpected passing away of the property owner of the land our range was located on, and the property owner's family not wanting to rent out the property any more, we have sold all our benches and equipment, shut down our Iowa 1000 yard range, and are no longer holding matches.
