270 is too close to 3006 for me, might as well leave the 06 barrel on it. I'd like to either fill a gap in calibers, like the 35 whelen, or build a light recoiling deer hammer for one of my kids, like the 257 or 7x57. I'm just not that into the 270, I don't know of anything it can do that a 3006 can't do equally or better.
