I keep going back and forth on how to load it. Right now it has 158 grain flat nose semi jacketed .357 magnum from Gold Country ammo in it. That's it in the speedloader. I've also got plenty of assorted .38 special + P available. Hydra Shok, some kind of Remington 125 grain JHP, and a 125 grain JHP also from Gold Country. My thinking goes like this but it's not so firm as to not listen to reason: If for any reason that 686 is ever fired indoors, I want maximum effect as soon as possible. I think in a situation like that the additional noise and flash of .357 v .38 are outweighed by the .357 performance. I can handle either round. The sights on the 686 are regulated to ten yards with the flat nose .357. So, what do others think about this?
