A client I had out to the range last week pointed this out to me, yesterday. We talked a lot of shop, including hand loading, and both of us hate the time taken to trim.
Looks to me as the same principle of trimming, chamfering, deburring in one pass as the Giraud. But you can provide the motor, and adjusting the location of the cutter is much easier with this design than the Giraud. I think I'm going to go this route. I'll save me about $200+ versus the Giraud.
Be sure to watch the video. He did a great job of showing how the tool works.
I'm thinking I can get away with not having to buy a die for EVERY case I trim. Yesterday I researched shoulder angles, and it looks like certain dies will interchange with more than one case.
.243 20° shoulder
7mm-08 20° shoulder
.308 20° shoulder
I'm fairly confident the 308 die will work for 7mm-08, but am reluctant that it will work well for .243, there may be too much slack, all I can do is experiment.
7 Rem Mag 25° shoulder
300 Win Mag 25° shoulder
One die there^^
6.5 Creedmoor 30° shoulder, it gets its' own die.
I retired a bench drill press from the metal shop, when I went to a floor model. The bench drill press has lived on the loading bench for years. All it does is clean primer pockets with an RCBS brush chucked inside the Jacob's. I'll report back once I use it some.
