I’ve never tried the boiling water, is hoppes or collings solvent not similar result ?
I definitely intend to get back on the range with some decent ammo for the next shoot.

Greetings Luke 566,
If any of the cartridges you fired were CAC or other WW2 you need to clean the barrel with boiling water. Military primers up to about 1950 deposit potassium chloride, a salt, in the bore. this can rust the barrel under an oil film. I used to pour a jug full of boiling water down the bore. Easy to do in a Lee Enfield. Oil after air drying.
