Derraco Engineering Ugly SRT Shoulder Referenced Brass Case Trimmer - Simple, Precise, and Fast

I think it's a really good value. It only took me like 5 mintues to get going on it. It's easy to use it, and it basically only takes maybe 5-10 seconds per case or less to get done. It's very durable. It's a good design. Everything fit and worked as it should. Glad I bought this. You just need to get one case the correct length and then you set it based off of that. It is not perfect, but it gets them within range. I set it to 1.150. Most of them came out to be roughly 1.145-1.155. That's good enough for me. It has a clean cut, and it does the job decently fast. I found that going kind of slow at first helps it dig in better. Give it a quick pause to let it dump out some of the shavings, and then full speed. I am using a hand held drill. Works like a champ. A good alternative to expensive trimmers. Just set the drill on the work bench if you have a battery operated one that can be set down so you don't have to hold the drill. One hand to work the drill. One hand to hold the case. It's much better than holding the drill the whole time. It doesn't appear to be getting dull, but if it ever does I would buy another one.

Works exactly as described, very fast and efficient, easy to get the right trim length.

Should be in every reloaded tool kit. Once they are setup, which was very simple, the process is so much faster and very precise!

I know that this is a copy of Little Crows perfect trimmer. Never tried theirs, But this one is made well and works as it should, their annealler is next. Just remember to size brass first then trim.

Best case trimmer around. Make sure to have a set of shims around to help set trim length. The design is simple, but it’s easy to make accurate adjustments. Being able to swap calibers is nice, but I end up dedicating one for a specific barrel. This is a solid 9/10, but would be a 10 if it was able to chamfer/deburr similar to the Giraud.

Very handy. This is way nicer than the Frankford arsenal one. This one uses an end mill and works amazing in my drill press. I very quickly trimmed 500 .223 brass in a couple hours maybe. I took breaks while trimming so I don't know how long exactly it took me to trim 500 rounds. Overall I am very happy.

Actually works way better than I expected, used to trim 30-06 brass.

Solid product! I went from using the Lee case trimmer to this, and will never look back. The Lee worked fine... but this thing is a dream! Chuck it up in the drill, and go to town. I can trim 200 cases (all within .001) in an hour or so with this. Changing calibers is a snap too! Two things to be aware of though. Depending on the caliber, (Im mainly trimming 300 Blackout) the amount of case that is sticking out of the tool is limited. As a result, your fingers can get fairly fatigued pretty quick. I find that wearing Nitrile gloves helps alleviate this a little bit. Also, it can throw brass shavings all over the work surface. Again, not a deal breaker at all, and I find that trimming over a box catches most of the trimmings.
