My Revolver and some of the cast bullets
A picture ofthe same bullet coated:
Bullet are casted from a Lee 358-158-RF 2cavity mold dropped .360 and sized to .357, alloy is 1part linotype and 2parts of stainedglass lead. Giving a Brinell hardness aircooled around 15. Since I needed these bullets to work with 357 loads I suspected the alloy to be to soft without gascheck and I was right. I got alot of leading in the barrel after only 5rounds and the grouping opened up the more that I was shooting. I forgot all kind of shootingrest so result would probably be better in a shooting rest but I got the picture. Took some support against a bench and shot at 25meters.
This is the group (25meters) with leadbullets with ordinary lube well it didnt work out, ran it through the chronograph and got 1338fps, severe leading in the barrel so I stopped and went to my powdercoated ones. Image is upside down but you get the picture
This is the group (25meters) with the powdercoated bullets, they also ran at 1330fps and gave no leading at all barrel was completely clean and the group was fine even though the support on the bench was not the best. Image is upside down but you get the picture
Conclusion is that the alloy is to soft for 357 magnum veolocity without gaschecks since its a nongascheck bullet I tried powdercoating them and it worked out fine. This is a bullet and a load that I can use.
