Those Matrix bullets are nice, I have some 165's right now. I also did a 270 WSM already, once I get the feeding issues straightened out I'll start getting her tuned in. I'm also going to rebarrel my 6.5/284 with a MRI barrel and chamber it in a regular 270 Win.
We are thinking bigger now, and with the 150gr ABLR it could be really sweet at 3500+
