I think i should post here.
I have a valve spring tester and it goes to 700psi..handy tool
Now i took 1 powerbelt hp copper series, and removed the skirt, then
cut off the little nipple.
I cast some lead bullets of my own with soft lead , that i scored at the ,well who cares.
Anyway i put the bullets base to base and compressed them at the same time to 50 psi.
I then measured the bullets,. PB =.633" long.......Homecast(HC)=.737" long
I then turn up the pressure to 550psi, let them relax about 30 seconds ,
then squished them to 650psi.
I then measured..PB=.535" long and .525" diameter
I also measured...HC=.395" long and .572" diameter
Not what i expected...
