Stan, reread what I wrote. I'm not talking about "wiggle room" or pushing anywhere close to the edge. Nor am I using a damascus or even an old gun. A 1990s vintage Merkel with 3" chambers and relieved forcing cones is not your bud's Boswell, now is it?

Please find a load that is published as safe for lead and unsafe for Bi. The published loads I found are quite the opposite. What is safe for one is safe for the other.

While I agree that being careful is paramount, staying in bed all day might qualify as "too careful". We could, in the name of carefulness, simply melt down all of our shotguns, couldn't we?
