Hi I recently aquired a L.Day swivel breech rifle.After taking it out of the wood box and following the assembly instuctions given.I took the gun out to fire it.Using the barrel with the serial# as barrel one.I have consistent good ignition from it but barrel 2 is failing to fire on the first shot.The second cap though sets it off.We noticed a litle looseness at the swivel point so we took it apart and tightened it hoping this would solve the problem but it still is not consistent.Also I am sighting it in for maxi balls.Will round balls shoot at the same point of impact.
