I seem to recall in a long ago (ca. 1978) article in Guns and Ammo of a such a beast; custom built. Anyone recollect that as well? I'd like to see that publication again.
If I recall it was a custom made, I would say a little to much for the rotary action. Many years ago a friend of a friend had a 300WM shear the rotartary lugs and it was lodged in a cracked receiver at the rear, no one was injured could have been a handload pushing up the pressures. lucky in my book since most over pressure results with a failure just forward of the lands right where your hand is.
