Upland ,the shot size for pheasants remains a debate in whatever crowd you are in!My dad has been hunting pheasants for lil over 40 years,me for a lil over 20.We have used a little bit of every combination,from 2 3/4 high power to 3in mags,4 shot to 6 shot.I havent used 7 1/2,though at close range and fast enough I suppose they would work.I have tried #4 shot and didnt like it because it pulled so many feathers inside the bird and close range shots cut the bird up alot!I have loaded #5's and #6's and they work fine,still gotta be careful with those shooting close and tighter chokes.I love to reload the shells I hunt with,but until recently,I discovered the newer Federal Wingshok 1500 fps 1 1/4 # 6 load and IC choke in my Legacy.This load has alot of energy with the fast speed but the smaller #6 shot has the density and doesnt pull the feathers in so bad.It will kill the birds if you hit them!I was really impressed with this load.If the birds are coming up really wild you can use the #5 shot load and IC or mod choke if the shots are really long.Adding the velocity to the smaller shot sizes really boosts performance.The Remington Nitro Pheasant load is nearly as fast and works about as well.I have used both.They both are relatively inexpensive,bout $12 a box depending where you buy them.The birds we hunt are all wild birds,some even the old tough hill birds from around Chamberlain around the Missouri river!Whatever you use shoot straight and you will kill em!Good luck to ya!
