Ryan, any 12ga load that has pressure around 8 to 9000psi should be safe because it will have less pressure in a 10ga because the chamber has a bigger diameter for the pressure to push against. I usually stay away from BPI because their components are more expensive than after market components. Most of their loads are for what they sell. I know they sell some things you can only get from them, but other than that I don't buy from them. I can buy CB 12ga wads for 80$/5000 [ or $8/500] - about half of what they get. I think you'll find the Rem, Win, or Federal 10ga hulls will last longer than the Cheddite hulls. I know loading 12ga the Cheddites are only good for about half the reloading life as the American hulls.
