30 Caliber
RCBS delivers again 22/03/2016
I purchased this set with the 7mm attachment (no particular reason, I needed more calibers anyway). Once received, the quality is there. The bit tip is very sharp, and the handle is soft on the hand, as well as offers great grip. The neck collet uses a standard allen screw to set, and doesn't require much force to set and stay. I myself didn't use the handle as I had hundreds of cases to do, so I just chucked the bit into my drill and went to town. Once the depth was set, which spaces off of the mouth (so the brass must be sized and trimmed to be uniform) she runs like a champ. It takes 1 second of cutting on medium speed to get the results desired. I did try with the handle, and it works, but it's very slow and tedius, along with making it look like a beaver chewed on it. That is no fault of the tool, it's because I didn't have enough RPM using manual labor to make a nice clean cut. Using the drill though, flawless. The one thing I would suggest for RCBS would be to make this a drill only specific attachment, otherwise, great job.
