The melting point of the lacquer on the cases is really high and it would take a lot of rounds to generate enough heat to melt it to the point of sticking in your chamber. But the bees wax will melt after a few rounds and cool off and harden pretty fast too.

Also make sure when you lean the gun after use, ghat you use a solvent that will neutralize corrosive salts that can be left behind after using Russian ammo.
The best and the most successful way to clean the chamber on a Mosin is; take a 20 guage brass bore brush on a cleaning rod and an electric drill. Use any bore cleaner and brush the hell out of it then clean as usual. This will not hurt the rifle. Your Grand Pa is right it is the laquer, and the casing does get hot enough to melt the laquer so it sticks to the less hot chamber. I had sticky bolt syndrom when I bought my first Mosin but it will shoot any ammo now. I use the cheap laquered ammo most of the time so I need to do this again but it has been about 300 rounds since I've done it. You can try all the other remedies but you will eventually end up doing this.

You wouldn't had to pull the 7.62x54R to make brass for the 7.7 Arisaka, simply use 30-06 brass, pass in die one time, trim and you are in business. load with .312 pills

BTW, IME these "chamber cleanings" usually take a couple of

range trips to melt out all the Cosmoline. It helps to bring rags

to the range.

Another vote for polishing the chamber with a variable speed drill and a worn out brass shotgun brush. I lubricate the brush with kerosene or mineral spirits.
I also do this with my single shot shotguns and they now eject the empty almost over my shoulder.
