Yes, I agree. I do mine in the garage & I periodically open the door, although it's pretty draughty in there anyway! On occasions I have bead blasted the rust off a partially used up anode. It 'refreshes' it by taking it back to bare metal.
Cleaned up a nice round with the Government Cartridge Factory No3 headstamp earlier. Not exceptionally rare, but a little less common than Kynoch, Greenwood & Batley & so on. 1917 dated & probably a Hindenburg Line find. I gather the site of Factory No3 was resurrected in WW2 to become the Blackpole ammunition factory.
Following on from earlier comments, Kynoch cases are also rather prone to neck splits, although both Kings Norton & Rudge Whitworth seem to have produced (or sourced) excellent quality brass. Only anecdotal I know..........
With two thousand rounds of dug up ammo & my electrolysis kit set up, those long winter's nights are simply flying by! (Apologies to Captain Edmund Blackadder).:madsmile:
