I was referring to the carbon stalker they came out with not the HS precision carbon. I cannot remember the exact weights. Somewhere around 5 lbs? But they only come in short actions I believe.
I think a 308 is a fine caliber. Personally, I have taken moose, bear, caribou and sheep. I did worry when I first got it that it light be too light, but I have found that monolithic copper bullets, or really any quality bullet is key. Haven't taken any large bears and keep my shots to within...
