[QUOTE="44-40, post: 2856936, member: 126985"] All you have to do is get some 6.8x51 bimetal hybrid cases form them to 6.5 Creedmoor and see for yourself. You can witness on video the 277 Fury hybrid case fired in a 277 Fury chronographed the 140 gr and see 300 fps increase over the civilian 6.8 Fury brass case in a 16" barrel and the manufacturer stating 3200 fps in a 24" barrel. Its just basically a 277 bullet in a 308 Win with a 30° shoulder...with an 80,000 rated case head of SS. Just neck it down, and push the 30° shoulder back a bit and add a .264" bullet and the 6.5 Creedmoor is a whole different cartridge. Works for anything off the 308 case, 243, 7mm-08, 308, 6.5 Creed, even a 6 dasher if you care to do some case work. The improvements are real, some work better than others, and powders to make it all work for all calibers is likely hard to find as the one manufacturer claims over 60 blends tried before settling one the powder...but proven improvement there for those who care to experiment. I have reloaded them several times, and the primer pockets are still tight...these cases will take well over 80,000 psi so be careful using them. And of course reloading them is not recommended and will void factory warranty as many manufacturers say about using reloaded ammunition. As always it's your call, whether to pursue the hybrid cases extra performance increases, or not,...but the extra performance is there for those who choose to pursue it...to deny it exists is foolish.
