Lee Zip Case Trimer

[Rory McCanuck]

I really like mine. A quick zip-zip and brass is trimmed, chamfered, de-burred, and cleaned with steel wool.
I'd like to make an adapter to accept the RCBS primer pocket brush, rather than my drill.
About $6/calibre is still cheaper than pilots for the hand crank style trimmers.
Only real downside is you have to trim before the brass is primed, so it adds a handling step to each brass,
assuming you prime on the press. If you hand prime, it makes no difference.

It might seem that it can't trim square if your brass wobbles, but the pilot holds the cutter square.
It works well, and its certainly inexpensive enough to give it a try.

I looked into a zip trim, the problem is that you need the particular length piece for each caliber. I shoot and reload a lot of oddball cartridges and there aren't even guages made for those calibers. I decided against getting a zip trim and went with a lathe style trimmer so that I can set the length myself. I also did the math and even for the calibers that I shoot that are common, five-eight seperate calibers is 30$ for the zip trim plus the cost of each of those guages (~5$). So the cost of being able to trim 5-8 calibers is actually 55 to 70 $. Thats getting into the range of most of the lathe trimmers which let you do any length that the lathe can fit...
