John,
I have been useing Kent "Impact" Tungsten Matrix Pheasant loads. They are 1 1/4 oz of #5's at 1400 fps. I agree that this is over kill on velocity. I prefer 1200 fps, but this is what is available. I purchased several flats of this stuff in 12 and 20 gauge a few years ago for $12.50 a box of 10. Another way to go is NiceShot that you can load yourself just like lead with no buffer or order shells from
www.rstshells.com Their velocitys are more to my taste.
