With 4" S&W M66 using 158 gr .38 spl handloads that have chrono-ed at about 900 fps. Anyone with experience who can offer advice, etc? I haven't done much in the way of distance shooting, but decided to check out this combo--my everyday carry--to see whether I can hit the side of the proverbial barn and how much drop at that range. I was able to place most shots on a silhouette with my forearms resting on the shooting bench. XS says to center the front dot on targets up to 15 yds and the top of the dot beyond that. At 50 yds, centering the dot seemed to place the shot best. I didn't try offhand at this distance, but to my surprise I find I can't do well from braced positions shorter distances. Can't figure out why the heck that would be and it is very frustrating since I am hoping to improve accuracy over offhand.
