[QUOTE="AZShooter, post: 919600, member: 5219"] The 6.5mm Mach IV IS the 264 win mag. It is a SAMMI adopted cartridge and has been since 1959. The 6mm-264 really isn't obscure just a bit crazy. It is the natural progression for a typical rifle looney that loves to neck cases up and down. The task of doing so is the easiest way to make a wildct. When many cartridge designs were unveiled the gun nuts had to neck it up and down. Happened with the 30-06, 308, 7 x 57, 284 win, and more recently the 375 Ruger. Heck the 375 Ruger is pretty much the Dakota reincarnated with a smaller rim diameter. Many of the early wildcats have become standard cartridges and it is still happening today. When Winchester came out with the 264 win mag, 338 win mag and 458 win mag at the same time in 1959 that case was immediately made into a 308 and 7 mm. The folks got fooled when Winchester later came out with the 300 win mag and it wasn't a necked up 264 or necked down 338 win mag. That 30 cal version is still called the 30-338 win mag. It is shorter than the 300 win mag with a longer neck. It is very similar to the 308 Norma mag. It took Remington to make the 7 Rem mag and it sure wasn't what Warren Page championed in the 7mm Mashburn. When the 300 WSM came out it immediately became a 6.5 and a 338 And there was some necking up and down for the WSSM cases. I think you get the idea. pretty normal stuff, just more costly. I must admit I get swept up with the fever and I KNOW performance wise that I am not going to create anything that hasn't been made before but it sure is fun! [/QUOTE]
