Bill, I live in the KC area and last year I became interested in trying to shoot some smallbore rifle silhouette. Unfortunately there just doesn't seem to be any venues for this activity. Topeka has a couple of "fun shoots" (read unsanctioned matches) during the year and the other places I found were all on the Missouri side.
Some other options for you might be to go check out the Lake Afton range where they shoot IHMSA smallbore silhouette. I think that they were talking about setting up a bank of 1/5th scale targets...granted they are at IHMSA distances of 25, 50, 75, 100 yards. In my limited experience, this translates into about 3-4 more targets for the beginner. Another possibility is to drive a couple of hours to the range where I shoot (Williamsburg...about 30 min past Emporia) where we shoot IHMSA silhouettes. I know they always have a set of 1/5th scale targets set out at matches and the match director would certainly let you shoot your rifle at them (assuming you follow standard rules of no hypervelocity ammo). Generally I bring either my cowboy rifle or my Finnfire to the match as I like to shoot rifles and pistols.
