475 TREMOR
**LATEST UPDATE - 30 SEP 03**
My 475 TREMOR is the work of Tony Rumore of Tromix Corporation. Tony is well known for his exciting variations on the AR-15 platform. The 475 TREMOR cartridge is the creation of Marty ter Weeme of Teppo Jutsu and is a necked-up version of his 458 SOCOM, which is a new, proprietary cartridge designed to deliver .458 caliber bullets from an AR-15. The 475 TREMOR is an exciting way to launch 230, 250, 400, 500 and even 600-grain bullets from a magazine fed firearm. This upper was Tony's prototype and to my knowledge, the only one of it's kind. My 475 TREMOR upper is built in the ultra-light configuration instead of the standard heavy barrel variant. Tony recalled that Tromix only built five other light weight units, two ultra-light .458's and three ultra-light 50AE's. The DPMS high-rise upper has a 16", Pac-Nor Stainless 1:18" twist match barrel. I purchased it from Tony after he decided to discontinue his adventure with Tromix to focus on other avenues. Due to it being a prototype, I had custom reloading dies cut by CH Tool & Die and brass will be made by reforming 458 SOCOM brass. I will update the information as often as possible as I discover the true potential of this monster. Watch the Reloading Data page to see how much speed and power I can glean from the TREMOR.
