Most all products with ammonia advise to not let sit in the barrel for extended periods of time. Montana Xtreme products are the exception (I believe) due to being oil based. The ammonia safely evaporates leaving the oil behind.

If you plug up both the chamber and the muzzle, would this keep the ammonia from evaporating? If so, would the M.X. products be just as hazardous to a barrel as CR-10 or Sweets when used like that?

Just wondering...
