    What if I told you ......

    You can harness the power of the 416 Rigby, 416 Remington or the 416 Ruger etc .... in a cartridge shorter than a 300 WSM ?

    And there is an action that was made specifically for it and you can have a complete rifle built for you, along with factory made brass available for it ?

    The 416 Thumper concept is a simple one, yet very effective in achieving the criteria presented ...

    Cut 375 Chey Tac brass to length and neck down to 416 caliber , shoulder angle and body taper optimized for proper feeding and extraction with ample case capacity to use modern powders that are not temperature sensitive to recreate the velocity/energy and notorious killing power established by the great 416's on dangerous game all over the world

    The 416 Thumper is the first of a complete line of cartridges in calibers from .30 cal to .50 cal designed for the "Thumper" action developed by Pierce Engineering in Michigan, USA

    John Pierce does have the 338 Crusher cartridge and action for it available to the public

    basically a 375 CT case cut down to 30'06 length with over 130 gr h20 capacity and 3.850" AICS/Accurate mag compliant even with the long copper solid bullets

    My wife just looked over my shoulder as I was reading up on this. Lol I got a stern NO. I guess it’s back to the closet with my I pad.
