I've shot quite a few clay birds with 5/8 of steel 7's at 1300. Wonderful light load. Used 7/8 of steel 6's for long birds. But I don't use them in my tight choked Cashmore. Not on purpose at least, I did put a few of the 7's through by mistake once with no discernible damage. I'd be happy to use them in a similar gun with less choke.
