Thanks for writing this up, Gordon.

Generally, the trouble with the Shultz dry-lubed method, is the fouling buildup shot after shot as there is no moisture to keep the fouling soft.

Some State's-Side shooters have used this system for match shooting where they clean between shots anyway, due to the time between shots, as in chunk or the turkey plank shoot.

For a hunting rifle, I'd have no part of that system & would use an oil or grease, such as Neetsfoot oil, Mink oil/grease.

If it works for you, then stay with it.
