I didn't even know that OKC had Field Target until Dave Cole was kind enough to speak out. I will need a new/used rifle to participate. It's my understanding that they do not allow a poor man to throw rocks at the targets. So I'm looking at various FT veteran springers like Weihrauch, Diana, and Walther. Occasionally someone will let slip a comment that the .22 model of the same rifle shoots smoother than the .177 version. Usually in a UK forum. Is there any truth to that?
