Power case trimming

42 posts in this topic

We had the topic of power case trimmers on the old forum. I think some of you would be interested in it again. I have reloaded for what seems like forever, over forty years. I started as an inexpensive way to get ammunition for my centerfire guns and shotguns. The part I disliked and took the most time for me was case trimming. It is a necessary evil related to reloading. From my old trim dies and a file to Forster trimming tool to a Possum Hollow case trimmer. I would sort my cases just to keep from having to trim and then grudgingly trim a bunch at a time. The Possum Hollow case trimmers are nice and if you don't mind using an electric drill then it is relatively painless and somewhat faster. But it still isn't the perfect solution and if the Possum Hollow trimmer isn't held correctly and cleaned regularly it just doesn't cut enough. It can produce a great callus or blisters after a hundred cases. This is because you try to rotate the case in the trimmer to get all of the brass trimmed. You also have to chamfer the inside and outside of the case separately. It works and I've done thousands and thousands of cases with them. I was looking for something to do hundreds of cases at a time and I researched the two true powered models. Both of these models trim as well as chamfer the inside and outside of the case. This is the real time and finger saving procedure. The Gracey and the Giraud. The Gracey is powered but is more of a powered pencil sharpener. It is also quite messy as the trimmed brass goes everywhere. It is very similar to a powered Possum Hollow just faster. It just isn't built to the standards of the Giraud and you can see that in the pictures. You'll want to wear safety glasses and a face shield using the Gracey. There is a protective shield that is supposed to keep the brass in but it doesn't work well. It also gets loose and lost rather quickly. The Gracey has a tendency to not clean the shaved brass as well as the Giraud. It works but is not the finely machined and built trimmer that the Giraud case trimmer is. Here are some pictures and links for you to look at if you are interested in any of these.Possum Hollow Kwick Case Trimmer about $19 per caliber plus holder.http://www.sinclairintl.com/cgi-bin/catego...5-7X&type=store05-7X.jpgGracey Power Cartridge Case Trimmer about $277 one caliber.http://www.matchprep.com/trimmer.jpgGiraud Power Trimmer about $365 one caliber.http://www.giraudtool.com/index.htmgiraudcasetrimmer.jpgA final note here about my Giraud. I bought several calibers for my most used rifles. There is some setup time changing the tool heads but not bad. When I first got the Giraud I retested some of my formerly trimmed brass. I was shocked that there was brass that hadn't been removed on some cases. I found this due to the fact small shavings were coming between the case trimmers and the trimmer itself. This didn't allow the case to be fully trimmed. The Giraud because of it's design allows the trimmed brass to fall down and away from the case and into a clear material compartment. You can easily see and empty this when necessary. I have been able to do thousands of cases a day easily. My wife even did 4000 cases for me one afternoon just sitting on the patio. That paid for the trimmer for me. Either model or design you use these models speed up the process of case trimming.Best of luck...John

Next time you get it setup and running would you take a couple of pictures for me? I'd like to see where the holders and shells are going.

You measure the cases with a micrometer. Or after full lenght sizing they have guages that will tell you. Some people just wait until the bolt is harder to close and trim after that point. It's something you'll learn as you go along.

I just sat in the garage and deprimed/sized 350 of my 223 cases. As I sat watching that pile of brass grow I kept thinking about how much easier this little baby would make the the trimming and deburring process! John, you know you're a bad influence on me, right?

He sure is. I was happy using my balance scale and then he got to talking about that RCBS 1500. Now I'm short about $300 in my checking account. He is a bad person. :huh:

I'm just making your life easier for you. :huh: I wished they'd have had these tools when I started reloading. They are somewhat expensive but what's your time worth. Plus they are very precise tools which is extremely important in reloading. I don't think I could go back to the old ways ever again. Let me see, what do you guys need next? :huh:

Well, since I am retired, and have all day to do what ever I want, I guess my time isn't worth too much. :huh: But, it is going to be fun to just play with the darned thing. By the way, I have not received it yet. My wife got it for me for Christmas, but it was backordered at Natchez and it is supposed to come in Monday. I don't think I could go back to the old ways ever again. Let me see, what do you guys need next? More money to buy the toys you all seem to have? :huh:

Chronograph?
I assumed you had one. They're a must I have two. I love the little printer on mine so I don't have to remember to write things down. :lol:

I noticed over the weekend that it is a lot eaiser to start the bullet seating process with that slight chamfer this trimmer puts inside the case neck. Make that bullet a boat tail and it is really easy!

Even if you don't have a Giraud trimmer like ours you really need to ream the inside and outside of your case necks. It can be hard on the finger with that little tool so I used to use it in a cordless drill as it goes so much faster.deburringtool.jpg
