10:1 alloy

[RSVP2RIP]

Is anyone using this and having good results? I've cast for muzzleloader for years and I'm going to start for .38 spl. I'd like to stay with alloys that have only lead and tin in them because plumbers lead and 50/50 solder are free to me, kinda. I don't know where I could get antimony around here (other than in 95/5 solder) without ordering it, which I imagine shipping is expensive. I heard that having high tin in the alloy causes the bullet to soften over time, is there any truth to this?

They should work fine in a .38 Special.

For light target loads and such, a softer alloy then most people use is actually better.

A soft bullet will "bump up" at lower pressure to fit the cylinder throats & bore.

A hard cast bullet won't, and you may get worse leading with a hard bullet then a soft one with light loads.

Consider that just about all factory .38 Spl lead bullet loads are soft swaged out of near pure lead. Same thing with .22RF bullets, and we shoot them at 1,200 - 1,400 FPS without leading don't we?

Specifically I want to recreate the old "Super Police" load with a 200 grain bullet. Since those are only going about 700fps soft is ok then? I was loading Meister hard swaged lead SWC 158gr and I thought that the accuracy wasn't near as good as the guns were capable of with jacketed. Nothing wrong with the load I was using either 4.0 gr Win231. It was the best of the ones I tried, never thought it might be the bullet was too hard.
