JB, you should do an updated article on the 7x57 with modern powders Like you did for the .264, Include Reloder17 and Ramshot Big game as they seem to be in the right burn rate to be real useful. All the data out and about seems to contain H414 and various 4350s but not AA4350 also....
P.S. any updated 7x57 article should also include extensive details about throat dimensions.....
In case you are wondering . I am still looking for a good setup for a rebarrel project
