I just wrote a response and it disappeared,oh well,try again,I started using rio ammo a couple of years ago and really like it,I use to use whatever was on sale usually remington sure shot,the rio seems to shoot alot cleaner,better powder I guess,seems to pattern better in my gun,I use heavy game loads 7 1/2,if i think shots will be long for the day I go with the high brass long range @ 1335 fps,but that stuff sure puts a whippin on my shoulder.I have never heard of steel shot on doves,but I have never hunted them outside of Texas,only thing we have to have steel on is duck and goose.
