My personal favorite is one of my 329s. Long ago I discovered its a great 44 Special. Also in the distant past I stumbled upon some 300gr full house loads, Speer or Sierra or something like that. They were 20 to a box and I managed to buy 3 full boxes for very little.
My little game is to stage my loads. I make double sure the first 2 rounds are nice tame handloads in 44 special. Even those will let you know they went off, but nothing like a 240 gr loaded magnum, and no in the same game as the 300s.

So when you've got some newish fools and you're not shooting seriously at paper, out comes the 329.
The trick is to fire one special, then complain about how it hurts. Then you fire the second and last one and declare how bad it hurts. It seems to bring out the macho in some guys (victims). Then want to try it...
When the first 300 goes off almost all hand the gun back to you. Occasionally there's a tough guy who tries a second shot. I've never had anyone want a 3rd. Funny how that works.
Yes, the 340 or 360 also hurts your hand. The big guns are made out of huge chunks of steel.
