Thoughts and opinions on alloys for target pistol loads please. 38,-44spl,45etc
To the point: I suspect it doesn't matter
I have traditionally used wheel weight alloy with a measured hardness of 9 but those are drying up. For velocity around 800 max, l suspect the alloy doesn't matter as long as the as cast diameter is ok. Pure lead shrinks on cooling explaining some folks difficulty with it. Tin is available and it apears that about 1% helps properly fill the mould, gives a shiny "boolet" at bhn 11.
I have plenty of pure.
