Stuck bore snake in a minnie in SASS Wire Posted Wednesday at 06:58 PM · Edited Wednesday at 09:52 PM by Happy Jack, SASS #20451 It is easy to tell if the material is nylon or polyester. Take a small flame and if it is nylon it will be a strong acrid odor when melting/burning. If it is polyester it will have a sweet smell. Solvents are different for the 2 materials if you try the solvent route. I agree to try a worm.
