OK an update.......It now appears that the range salvaged lead will NOT be linotype, as many pistol bullets(including police practice ammo) is well below this standard.
I now aim to simply melt and cast ingots of cleaned lead and then get it tested for hardness somewhere- before going on with the project.
Also the nozzles in the shotmaker can become blocked, unless clean lead is used- apparently.
Spoke to a local ex-farmer this morning. As a child he made farm shotgun shot with a blow-torch and a steel funnel with holes ball-pened in it on his dairy roof. The lead went down the corrugated steel roof and then plopped into a bucket of water with a bit of oil on top!
Amazing what you can do in shortages.
I asked him what SHOT SIZES he made by this home-made process.
The reply was a cheerful "ALL SIZES"
