Hi
So a while back a picked up nearly 500 old .310 cadet rounds for free. Its jacketed ammo and is berdan primed. The ammo had been poorly stored in the back of an old shed, some of it doesn't fire and some get a slightly delayed response. I know i could, and probably should, pull all the rounds apart and reload the projectiles into new boxer primed brass, but I'm not set up for that yet. The cases are dirty and need to be cleaned before being run through the rifle to avoid filling the chamber and action with grotty filth. Any recommendations on how to clean the old cases before running them through the rifle? Brasso on a rag seems to be pretty effective but I'm thinking there might be something else?
Cheers
