First, let me say hey to everyone. I am new to the board, but not to shooting and reloading.

I have a series 70 colt that I have fired many lead swc through over the last 25 yrs. Havn't seen any adverse effects and have kind of taken for granted that cast .45's are great.
Now, I recently purchased a Sig P220 Elite (Dark) and am wondering if I should use these same cartridges or will this shorten or have any adverse effects on the barrel.

200gr SWC ahead of 6.1 Gr Unique w/ cci primers.

Ok, my bad. A search tells me that alot of guys are shooting swc in p220's.
Reading the thread on lead in .40 glocks got me a little concerned.

Yep, you're correct. As to the Glock barrel, keep in mind the rifling in a Glock is designed differently than any type I know of, and their manual specifically says NOT to use lead bullets. Apparently the rifling design does not interact with lead bullets well, and causes severe and excessive leading almost immediately. I've never done this myself, mind you, preferring to obey the book and not blow up a gun just trying to prove them wrong.
