Just bought a 905 Taurus 9mm revolver. I found that many of my reloads will not chamber in the 905. I discovered that the measurment just above the groove at the bottom of the brass on my reloads was .391 plus or minus. The factory loads which work great measure about .381, and sometimes I get a difference of as much as .012. So the factory loads fall right in and come out fairly easily. My reloads often won't go in far enough to close the cylinder. The measurment on the bullet end is fine, but it seems the resizer doesn't come done on the brass far enough to resize it for this revolver. I sent RCBS an email and I will wait and see what they say. But for now I will have to stick with factory ammo for this gun. It shoots really well and I am hoping I can get some brass resized so it will work in this gun.
