I have only shot factory ammo through mine so far, I still need to get dies for it. You can check out 450bushmaster.net, that is currently the place to get info for the 450. The creater of the 45 Professional, which Bushmaster shortened to make the 450 posts over there as Wildcatter.

The Calguns thread is a great source of information, but it has started to dwindle as a lot of the participants have moved over to www.450bushmaster.net
