Varies, but have settled upon Prvi Partisan as my preference. Inexpensive, and high power (the data indicate it has 720 ft/lbs energy in a .357 Magnum SJHP load at 158 gr). Switch to FMJ for my camping and kayaking outings, since there is always the possibility of encountering bears, and penetration into a very tough animal is more crucial I'm told.
Remington Golden Saber (because of the limitations of the USA Carry app for Android, I wasn't able to vote in the poll).
