So I acquired a CZ550 that was built by GA Precision as a 500 Battleship, Apparently a Rigby cut off around the shoulder and necked for a .510 projectile. I am have that rechambered to 505 Gibbs and am looking at doing some odd ball experimenting. Does anyone know of anyone that has worked up or QL-ed 750Gr Amax in the cavernous gibbs? I have an actual .505 Barrel to thread and chamber as well that was will go on it later in life.
 
I do not as the biggest I’ve seen is the 600 grain work up. Tagging this thread to stay informed.

I'm unfortunately on a diet. Presently in VA hospital as Agent Orange finally caught up with me. Cancer and I no longer can speak. If all goes well I'll be out of here and back home in Thailand by end of July. Tough road but I'm a tough old guy. I'll make it that hunt.

Nice one there. I guided for mulies and elk for about 10 or so years in northern New Mexico.
