I have a Lazzeroni Patriot (same donor case necked up to 30 cal. Get about 3130 fops from a 168 Berger. Shoots great but brass is no longer available and doesn't sound like it will for along time. So my Patriot is a safe queen. I would just go with a Gunwerks 7mm RemMag or 7LRM. You get 3100 fps from a 180 Berger. Superior in just about every way - I have \one of those too so speaking from experience. I have really enjoyed mine. Constant and predictable and expensive but I feel very good value regardless.
