Did you look at the Traditions firestorm rifles. Break open loads the bullet from the front and takes a firestick for the powder charge in the chamber, when you load the firestick you insert a federal 209 primmer in it.. The firestick contains the new triple 8 powder. I bought 200 grain firesticks for it and Hornady Shockwave 250 grn saboted bullets. The targets in the picture are from my .270 not the Tradidions.
