Lube Inside Case Mouth

[TIMMY]

I've never had a need to tumble brass before. Never had dirty cases really - just use a little steel wool around the shoulder cleans them up fine. Now that I'm playing with suppressed ARs, the brass is very dirty and I think I should tumble it. I plan on using the FART.

I've heard that tumbling removes the carbon from inside the case mouth and can lead to bullets fusing to the brass. My buddy had this happened with his 300 RUM and it ripped the brass off below the shoulder when he tried to pull the bullet after noticing the problem.

What is the remedy for this? Case lube seems to be the answer. But people also say to tumble the brass to remove the lube because it shouldn't go in your chamber. Tumbling after the cartridge is completely loaded doesn't seem right to me.....

I'm loading a few thousand 5.56 rounds and I don't really want to play with putting carbon lube into every case mouth.

These cartridges will be stored for possibly decades before shooting.

Suggestions?

Thanks!

i just lay out my bullets and spray them with one shot. Much easier to lub them than lubing the cases

And i can pick a bullet out of a dozen on the target that i accidentally touch with lube on my fingers

A hammer style inertia bullet puller will tell you all you need to know on inconsistent tension with older rounds...cold welding becomes obvious jmo
