Been hunting pheasants for over 20 years using nothing but Fiocchi Golden Pheasant #5. For the first 16-17 years did great, then started missing or getting more cripples. Blamed it on new shot gun, old age etc. Have a couple battery powered pigeon throwers so practice more than ever, smoked the clay birds but come hunting season and back to missing. This summer the light came on. Out of habit, I would just buy the yellow box labeled #5. Getting ready for this season, taking inventory of my ammo, for the first time I noticed 1485 fps instead of my old 1250. Found one dealer that had some 1250, bought and went to the pattern board. Shot several patterns to get a good average. At 40 yards, the 1485, 50% had a hole big enough for a Pheasant to squeeze through or at least less then deadly. The 1250? All but one, a partridge could not have escaped. Moral of the story? Like so many of you have hammered away, pattern, pattern, pattern. Live and learn.
