I finally have all the bits and pieces to begin casting the H&G Ness #38 safety bullet thanks in no small part to the kindness of Gamsek who without knowing me from Adam sent his MP version of the mould to cast bullets from. His kindness and assistance has left me speechless and mirrors the helpfulness of the membership more generally; this is a great forum and thank you all.
Now, to the question...
I have gathered up ten pounds of pure lead and twenty pounds of linotype so far, melted, fluxed and cast into 1 and 1/2 pound ingots. I have been playing around with the Excel alloy calculator from the sticky and it seems that I need to buy some solder (60/40?) to be able to add tin for given recipes.
I want to shoot these hollowpoints at subsonic velocities and want them to expand as much as possible or to fragment completely, what would be the best alloy for that purpose?
I haven't decided whether massive expansion or fragmentation would serve my purpose better and so want to do some experiments on various media. I would then be grateful for suggestions as to alloys for both types of bullet.
The particular bullets are gas checked and I have 50/50 Alox/Beeswax and RCBS 8008 indoor lube.
