hi, just started reloading for the 357 max, i have only tried 1 powder so far (imr 1680) found that 25 gr. with a 180 gr. xtp gives me 1 1/2'' at 50 yds. so i was wondering before i go out and buy different powers to try, what are your experiences with powers like, imr 4227, h110, 2400, or any others....? any input would be greatly apreciated. thanks.
