Check out Quail Creek Airgun Club in Green Valley. They host different shoots each Saturday. I believe they have both the Gunslynger (similar to speed silo at EBR) and Chicken Little.
I guess I wasn’t specific. I was talking about traditional silhouette shooting offhand. I am a member of Rio and only knew about benchers silhouette. The quail creek webpage doesn't open up for me it a blank page. I will try again later.
My apologies for not including this information. There is a website out there that QC no longer uses. They have a good link on their Facebook page. The last time I looked, you did not need a Facebook account to view their page. The listed link is http://qcagc.com. The phone number listed is (406) 698-1362. I hope this helps.
