[QUOTE="357Mag, post: 2348960, member: 106883"] Justa- Howdy, again ! Happy Thanksgiving to all. I sorta rushed my previous response, and wanted to touch on another topic..... If you want to fully exploit the 6mm Rembias would beington's potential, you should shoot powder( s ) that give you great accuracy, useful vel, safe pressure; and high load density ( IMHO ). For example..... don't shoot a case partially filled w/ Varget. Powders like H4350 and slower in " burn rate " would marry up well w/ long/longer barrel lengths. There was a time that a 26" barrel would have been considered the " long " barrel length for a 6mm, and a 24" being a common shorter offering. These days, longer barrels exceed 26" in length. And... as heavier bullet weights are used, the natural bias would be to go w/ the types of powders mentioned; above. The 6mm Remington has a long neck that already keeps the powder combustion " turbulence point " inside the neck. The " Ackley Improved " version features a shoulder diam blown out to larger diameter. This helps offset case capacity that was decreased by the sharpened 40* shoulder angle that Ackley used on the " wildcat ". The 6mm Remington cartridge was accurate enough that they offered it as a chambering in the " 40X " accuracy/Target rifles. With regards, 357Mag [/QUOTE]
