For those of you that have loaded the 358429:
I have several .357 magnums, and the 358429 looks like an interesting bullet to try. But...
One of them is a Ruger 50th Anniversary Flattop. A little math and a set of calipers tells me that .357 mag brass and a 358429 bullet will probably be too long for the cylinder.
Have any of you tried it?
The Smith and Wessons both have cylinders a good deal longer than the Ruger.
