Thanks, guys-that's exactly the information I was looking for.
So far, it sounds like the leading contenders are Federal Premium 158 gr, Federal HydraShok 158 gr, Winchester Silvertip 145 gr, and Remington 158 gr.
Since when I carry a revolver my reloads normally consist of 1 Speed Strip carried strong-side in an upsidedown Galco pouch on the strong side hip (immediately ahead of the strong-side holster), 2 Speed Strips carried in a Tactical Tailor Phone Case pouch (normally carried on the weak side hip), and one Safariland Speedloader carried loose in a strong-side jacket or pants pocket, Chuck's comment about the HydraShoks being a bit easier to load due to their shape and lack of exposed lead make excellent sense. Their muzzle velocity (1240) is also close to the S&B's (1263), so that should provide both a similar POA/POI and feel is my thought.
Keep the thoughts coming, guys-great input and much appreciated. Hey, who else but p-f can come up with with relevant .357 magnum effectiveness updates with the credibility of this thread's participants?!
Best, Jon
