Thanks for the info on the Garands. I knew about the M14 mods needed to safely fire the 190gr load, but didn't know a stock gas port in a Garand would work. Hell in the back of my mind I'm still scratching my head, as that load recipe doesn't follow the conventional wisdom of "Nothing faster than 4894 or slower than 4064" when talking about the M1 gas system. But then again that gas port is way out there at the muzzle so in a 308 M1 I guess having only 44gr of powder evens things out.

Did you ever get good results from the 308 chamber insert to convert a 30-06 chamber? Just curious.
