Yea I know this is not the convetional rifle cartridge but with a .685 RB and 135 grains 2F (no idea what brand here in Peru) it is not something you could say is underpowered. I was using 125-135 grains in a regular plastic hull but the hulls deteriorated rapidly. After 2 shots they were apt to seperate. This "cartridge" uses a standard Winchester wad "plastic patch" (the reason for .685 and not a bore ridding ball) that I modify to match the powder column adding other wads and cards as needed. The ball can also be seated deeper into the case with less powder. It does not seem to matter if the ball has the sprue up or down or completely removed "surgicly". I normally trim the shot cup pettals down to at least the ball height if seated inside the case. If the ball is extended then I trim them to the case rim but never shorter than the full ball diameter. An old Lyman catalog (reprint) showed starting loads at 85 grains 2F. Using 2f Black powder gives alot of versitility and loading options without serious pressure problems suddenly springing to life. I increase my loads at 5 grains incriments. I have not passed 135 as I have no need of any more power. My Mossberg Cylinder barrel is a 3" Magnum chamber. I soldered a german silver rifle sight at the muzzle and with a witness mark on the receiver gives "minute of paper plate" out to 45 yards. These brass cases are Remington and primed with large rifle primers. Fun to shoot and will certainly give you another Black Powder Cartridge option. As with all cartridge barrels slug your bore and match the ball to your barrel. Round ball does NOT choke down.. your choke will open up. :-(
