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.

Hi - the only (best) method of sending you the .375/06IMP data is with photographing my book notes. My camera died so the only way I can do it is with my phone. To do that, I would need your e-mail address, as this
new Android phone is too complicated to upload to my desk computer, which would be easier and to down-grade, reduce the file sizes.
Best wishes
Daryl

Hey Steve, This is Steve Washington we met at KMG last year. I am interested in your Winchester. Would love to speak with you about it. I work third shift and I cannot take a phone with me to work. Let me know a good time to call during one of your mornings. My phone is [redacted]. Live in Florida so I have to account for the time difference.
Look forward to hearing from you.

Good day, Slider.

Do you by any chance have any 500NE brass left that you are willing to part ways with?

Best regards,
Boela Bekker.
