257 Arnold Magnum

Does anyone have experience with the 257 Arnold Magnum cartridge? I recently acquired one-very nice rifle, but need some load data. I've been experimenting some, but haven't found that sweet load just yet. This rifle should be capable of some good performance.

Just for information sake, for those who might not know, the 257 Arnold cartridge is based on a 264 Win Mag necked down to 25 caliber. It was produced by Arnold Arms Company out of Arlington, Washington. They have since gone out of business, and the cartridge seems to be as scarce as hen's teeth. I can't seem to find anything on the Internet about it.

I'd appreciate hearing from anyone who knows about the cartridge or who has good load data.

Good Shooting.
 
pcammo,

Thanks, I may take you up on that offer. I'd really like to find a sweet load for this rifle.
