The Razor series do not have a parent case and can't be formed from any existing cartridges, New brass is made to my specs by a brass manufacturing company in any quantity I want and is available to the public
In wildcatting, people always say ... It's all been done before, Sure... if you keep using the same parent brass that has been around for ages, I no longer use existing cartridges for necking up/down and altering body dimensions, These are completely new case body designs that haven't been done before
The Razor concept was designed for use in Remington 700 and Winchester 70 long actions without altering existing bolt face or safety concerns of case body diameter vs tennon strength, Along with being compatible with AICS & Accurate 3.850" detachable magazines with high bc hunting bullets
The Headhunter series are longer versions for single shot use, they were designed to equate the case capacity of my Wolverine cartridges based on the 500 Jeffery case but fully compatible with Rem 700 actions, they also compare in case capacity to the 300 Raptor and 33 XC cartridges that require custom more expensive actions..
also have the dangerous game cartridges designed for use in Winchester CRF actions that will smoke the 375 H&H, 416 Rem, 416 Rigby and 404 Jeffery but in a shorter case length
