Hi, Guys -
The little bulge buster kit was pretty inexpensive, so I picked one up and have started toying with it. In my experience with 45s, I use a Dillon case gauge after sizing to assure each brass fits smoothly and flush. Simply for convenience, I use the case gauge rather than the barrel for checking the cases since I keep the case gauge on the bench all the time.
After sizing, roughly 5 - 10 % or so of the sized cases would not fit flush in the case gauge either at the rim or at the head right above the rim.
After running the 45 acp cases through the bulge buster (FCD), all fit flush and smooth. It appears this process perhaps "uniforms" the head area and rim of the cases. That's just my description, and it's probably not technically correct from an engineering standpoint.
Last weekend, I loaded 100 of the cases and brought them to the range. There were zero fails to feed. I used several bullet 230 grain types including RN plated, RN lead powder coated, Hornady XTP HP, and Montana Gold HP.
The pistol is a SR1911 with almost 1K rounds of reloads through it. I've never shot more than a handful of factory rounds. In the past, I've noticed about 1 or 2 fail to feeds per 100 reloads. The reloading press is set to have a slight camover using the sizing die, so it's doing the most it can do.
Having no FTFs out of the cases put through the bulge buster was a good sign and certainly encouraging. I will continue using the bulge buster kit and continue to monitor the results.
That's what I'm seeing so far with this process/tool.....
