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.

You might have edited your post on the PH in the Bubye. I know the PH and is a wonderful person and a fmaily man and runs a succesful business in Zim and just doesn't want the attention that the internet offers, the ugly kind.

Hello,

Am I reading your post correctly to say that the Tsavo rifle will be coming out with a composite stock later this year? I ask because I had been looking very hard for a Tsavo, but if there is going to be a composite stock model I will wait for that.

Thank you for your time,

Andrew

Saw your post. Nice. Denver too. Genesee area (just off 70) if ever up this way. Alternatively, do you have a membership at GGC? Whatever, you'll have a wonderful time in Africa. Enjoy.
