Hi everyone,
Have any of you ever fired a pellet at lead sheeting before? I am just trying to find out how much lead a .22 pellet will punch through when fired from a 12ft/lb ish rifle. I like the idea of having 2 sheets of lead as a backstop, the first one being just thick enough to allow the pellet through at greatly reduced speed and the second (around 15mm thick) to totally stop any pellet. I know a 15gram lead pellet will punch through 4 mm of lead at 130fps but have no idea what a pellet from a airgun will do. Lead also makes hardly a sound when it is struck compared to other metals which is another reason I like the idea of lead backstop.
Overall I want something that will safely remove the energy from a pellet with out the chance of a dangerous ricochet, i think a suitably thick piece of lead will do the trick nicely, what do you all reckon?

thanks in advance

Marcus.
