My best friend has a .270win Venture, and it's a great gun. Right out of the box it handles well and shoots great. I don't think the muzzle break on the .270 will do much more than blow your ears out. The .270 isn't a big thumper to start with. I'm a Mossberg guy, but my experience is limited to scatterguns. I've shot the Venture and I couldn't think of any way of getting anything better for around that price.
