Hello all, I am in need of load data for a 338gnr caliber, it is a 405 winchester brass necked down to a .338 bullet. I only have about 3 differents that have been able to find for it. Do any you fine folks out there have any info on loads for this caliber. I have gotten what I could from the nice folks at Gary Reeder Custom guns but only had just a few listed. Seems that searches on the net are coming up empty also. The gun is a contender barrel that I am shooting on this one is 12 plus a muzzlebrake making overall barrel 13 1/2 inches. Looking for all the good details, different powders, bullet weights, primers, velocity or whatever one may have. Thanks in advance for any help someone may be able to provide.
