Anybody ever put a MBE-12 box in a Weatherby vanguard? I'm currently using AICS mags with a coal max of 3.615 ish for my 300 win mag. Rebarreling soon and hoping to throat it long to get the 225 Eldm out where it needs to be with the top of the boat tail at the bottom of the neck or close. I emailed Wyatt's and they said they have never tried but that was it. The gun smith that will be doing the work said he doesn't know if it will work or not. He will just have to try. Figured I would ask before he tries and see if I need to just go a different route.
