Leading Testing

[ProudOkie]

Hey All, Have 3 alloys I want to see if they have any leading issues. Wanted to know how many of each I would need to fire before I could notice leading? is 5 an adequate sample? 10? Thanks!

Leading is not simply an alloy question. There is more involved. You need to do some reading. Pressure, powder, lube, velocity, etc. etc. All can contribute to leading, or not.

Every bit of information you seek is already on this website. Do a search or read some stickies.

I understand that alloy is not the only element of a leading discussion. I understand how it works, but am experimenting w my allow to see how little additions I can use to get little or no leading... so I have not seen on the site how many shots to test fire for such an experiment.

Just a simple air cooled, hunting alloy of 50/50, COWW/pure lead with a little tin added will lead after about 7-8 shots with a velocity of 1900 FPS while using good lube. Quench those from the mold or oven heat treat/quench and you'll get no leading. The bigger your test sample base, the more accurate your test results will be. I'd go with at least 20 rounds of each. Let us all know how your testing goes.

Well it was about a 8 to 1 lead tin bullet, leading after 2nd shot, after 5 it was way too full of lead to shoot anymore. That bullet shot fine w a unique load at about 1450 fps, not gonna work at 1800 w hodgens
