The breechplug/nipple configuration was very strange and did not match anything else that you could buy. If you needed a new nipple you would have a hard time finding one. I had one of the Scouts and killed one elk with it but sold it due to the strange configuration of the breechplug and difficulty getting the "false breechplug" chamber clean. It had to have the barrel cleaned like a sidelock since the breechplug did not actually come out.
