RE: 6.8 SPC
There isn't a need for nearly any of the cartridges we use today.
.22lr, .223, 30-06, 375H&H and a true big bore such as the 458 Lott. Everything else is a solution to a problem that didn't exist. [&:] Not to sound like a jerk but.........So what, who cares.
Until recently there has only been two .277 cartridges available, the .270 Winchester and the .270 Weatherby mag. It's about time that more manufacturers made more cartridges based on this bullet diameter.
I have not used one but I think it would make a superb round in a short compact rifle such as Rugers frontier or Remingtons model 7. I also think that all youth rifles should be chambered in this round. Encore handguns would also do very well with this cartridge.
It is easily a 250 yard cartridge for deer sized game animals.
