Bushveld beat me to it, I was about to make the same comment on Boiled Linseed Oil not being the same.
A method I've used in the past which works very well is to heat the barrel(s) with boiling water until they'te almost too hot to handle, then rub on melted pure beesway, the heat of the barrels lets the wax flow into all the angles, seams and corners. Set aside the part to cool,
When cold, polish off any surplus wax with a soft cloth, it leaves a beautiful and waterproof finish. It can be renewed if and when necessary
I suggested this method to an American friend of mine who has a lot of rifles and he was so pleased with it he doesn't use anything else on the exterior of his firearms. Attached is a link which shows a Highwall he rebarrelled, stocked, acid fume blued and waxed.
