The Rimfire Report: The Rare, Forgotten, and Weird RAU Wildcat 500

By Luke C.

Hello and welcome back to another edition of The Rimfire Report. This week we’re taking a quick break from our ongoing set of rimfire ammunition tests to check out another probably-forgotten historical piece – the Wildcat 500. Another single-shot .22 rifle with an unusual design and a brief but interesting history, the Rau Wildcat is one that I only learned existed just a few weeks ago courtesy of fellow writer Sam S. Today I’ll take you through what I’ve learned about the old rimfire rifle. Most of this information was gleaned from a combination of auction sites and various online forums as there is little official information on the Wildcat 500, let alone its manufacturing company, Rau Arms Corp of Kansas. Let’s take a look at this nearly forgotten rimfire rifle.More Rimfire Report @ TFB: The Rimfire Report: CCI Clean-22 – Part 2 with the P322 COMP The Rimfire Report: Musing Rimfire At SHOT 2025 The Rimfire Report: CCI Clean-22 Steel Challenge 40-grain – Part 1
