I have a lot of respect for Jeff but I have had two different 300WMs and two different 30 Noslers. The Noslers out pace the WMs by 100-150 fps. This is SAAMI 30 Noslers vs Custom throated 300WMs.Dont let that turn you off. I have built a lot of 30 Noslers and 30-28 noslers. In a 26" barrel a normal load is H1000 and a 215 Berger at 3080-3100 fps. I have hit 3200 with retumbo in the 30-28 nosler. Its just better than a wm in every way.
