Mark as you can see my screen name says what I love to do when I'm not hunting coyotes over the years I've loaded thousands and thousands of 12 ga. loads I have a MEC 9000 and love it, it the best for the $$$. I'll give you a load to start with,
this is my personal favorite load.
30.0 grains of Herco powder and 1 1/4 oz of hard 5's or copper plated 5's either work great and will knock the crap outta pheasants out past 50 yrds easy.
Good luck, Jeremy
