For busting rocks I opt for 1200 fps and mostly 1 1/8 oz #8 loads. I load a lot of Rex #1 with WIndjammer or AA or claybuster or RP wads. I sometimes use Unique or 700x depending on what I get a good deal on for powder. I load some 7 1/2s and 8 1/2s and 9s too! I like 7 1/2s for quail and the longer shots with Sporting Clays.
Field loads for pheasants is simple! I use Herco and 1 1/4 oz of #5s. The 3 3/4 dram load. Since Blue dot was introduced you don't see as many loads in 3 3/4 dram equivelent loads with Herco, but I still load mine the same way as I did 30 years ago. Might still have some I loaded 30 years ago to shoot up?? Not many pheasants arround here anymore! I have been gravitating towards the small guages past several years and I like 1 oz loads in 20 ga and 3/4 oz loads in 28 ga. I have a couple 8# jugs of Solo 1250 that works beautifuly in both. For .410 I like IMR 4227 with 11/16 oz of shot. I prefer #5s for everything larger than quail, and 7 1/2s or 8s for quail. I use the same load for clays as the quail load. 1200 fps with some running only arround 1145. I'm going to try a few of the 1500 fps 1 1/8 oz loads with Longshot this year if I see anything to shoot at?? I have a couple boxes loaded, ready to go. I tried Longshot in both 20 and 28 ga and wasn't all that much enamored with it relative to my loads of Solo 1250. They really hit like the hammer of Thor in the 12 ga loads though! You can really FEEL the difference too!
Heck, if we don't get any more pheasants arround here pretty soon, I may not even go pheasant hunting again so it won't make any difference what loads I use.
