My BIL says they have a guy at his range who shows up with a 6 1/2" barreled Judge and shoots skeet with it and does well, so it must be getting out there pretty good. I've got the 4" barrel, 2 1/2" chambers Judge and I think it would not do bad on quail, but you are right it does spread the pattern wide pretty fast. The Fed PD #000 BS on the other hand will put all 3 pellets in the 8 ring on a B-25 silhouette target at 25 yards and I would not have any problem using it on deer at that range. I think the performance of the Fed Buck Shot is not only in the copper plated hard shot but also the shot cups they use. I got the attention of the whole range one day. With the target at 50 feet, I hit it with the shot cup 5 times in a row. The slap sound it made hitting the target turned everyone's head to see what it was.
I think the real trick to getting good patterns with the .410 in a Judge is to use hard shot. The soft stuff deforms and sails.
Battle of Wanat: 10 years ago last 13 July, 1LT Brostram was killed in combat killing the last enemy combatant in the outpost. The LT went to the point of decision and made the difference that turned the tide of the battle. The original investigation found the Bde Cmdr, the Bn Cmdr and the Co Cmdr at fault for dereliction of duty. If you want to see what a sarcastic silver star citation reads like, pull up the company commander's silver star.
