Got an 1858 Remington stainless Pietta with the adjustable sights. One hole at 20 yards 20 grs 3f .454 cast ball. Powder first then fill the chamber with corn meal flush. Then the ball. No wad no grease. The gun is as accurate as any I own. The problem? cocking the gun. I almost have to use two hands to get the hammer back. I know there is a screw adjustment in the front of the grip.I have it so loose I am afraid of loosing it. Can I get another spring or is there a way to reduce it's strength. Obviously there are no cap issues. That hammer hits hard. Thank You and you all have a happy and rewarding new year.
