Not me. I've ended up with other guys' handloads a few times in swaps and stuff, but I never shoot them. Usually it's when a guy says "I won't be needing this and this and this," and throws it all in to sweeten the pot a little. I don't turn em down because I don't want to have the discussion with them, but I sure don't figure any value in someone else's handloads. The most use of any of it I've ever made was salvaging some brass.
