Yo Evan,
To keep the weight down go with a small contour 6.5 or if you just gotta a 6mm bbl at least 28" long.
For a cartridge, neck down the 270 WSM.
W/the 6.5 cal yer good for any animal in ID. W/the 6 yer good for almost any animal in ID.
If you want to get really hot, neck that case down to .224. Sweet
