Simple High Quality
It does exactly what you want from a case trimmer: square clean cut consistently controlled to the 0.001-inch. If quality is a priority for you, it's hard to find a better tool for the job.

Best Possible
There is no way to do it better than the method L.E. Wilson has devised & there is no finer micrometer than Sinclair's put the 2 together & your only complaint is speed... if you're making that much ammo this much precision doesn't matter to you, get a Lyman Xpress. If it's out of stock back order it, you need this tool if you're serious about tight SDs & tiny groups there simply is no substitute. Don't forget to order your caliber specific case holders, they usually ship both FL & FF in a single pack.
Awesome Product
Awesome case trimmer, super east to adjust. I can trim cases as quickly as my power trimmer, with much more precision. Less prep work after trimming as well. Should have bought this product long ago!
Outstanding Trimmer
I purchased this trimmer to replace a different brand case trimmer that I had used for many years. The older trimmer had served well but had gotten dull and was tedious to work with, requiring many turns of the crank to trim cases. It was also difficult to adjust when switching calibers. When the new trimmer arrived, I assembled it and did a quick test, using a couple of .223 cases. The micrometer adjustment is a quantum leap forward in accuracy and I was amazed at how quickly and effortlessly it trimmed cases to length. It has made an onerous task much easier and faster. Highly recommended!
Awesome Trimmer
Just got this today. I read the instructions and set it up and what a great trimmer it is. Each piece of brass I do comes out to the length on the dial and the trimming blade is so sharp it will cut 0.010 off in 2 revolutions. I had a Redding one that I struggled with because I could never just set it and go. I always had to check each piece. After using this one, I check maybe every 10th one. Once you get used to tapping the brass in the holder it's a great tool. Wish I tried it earlier.
Bluffton
This is an excellent trimmer. Very repeatable and precise. Although its supposed to be zeroed from the factory, the micrometer setting was 0.10" off on mine. Its a little time consuming to get the zero exactly right but after its set once it shouldn't have to be reset unless the blade is changed. I'm
My 2
As most other reviewers have said, this is probably the best manual case trimer out there. I was on the fence between this one, or, just spending more for the Dillon RT1500. My volume needs and the fact I didnt want to deal with the noise were the main factors here, so the Sinclair was the winner. So far Ive put about 600 pieces of 223 brass through it. According to my Lyman calipers, the micrometer is off by about 1-2 thousandths of an inch. Either way, I dont really care. You adjust were you want it, lock it down, and thats it. If you only trim one caliber like me (for now) it may never be adjusted again. The use of the case holder offers more than just trimming accuracy. It makes the brass much easier to hold for the follow up chamfering/deburring process which means less fatigue on your hands. I also ream out crimped primer pockets at the same time. I can perform all four steps on a piece of brass in about 22+/- seconds with only touching it once. Outside of how well its made, this might be the best pro about it. This thing could use one accessory in my opinion. Not everyone will need this, but Id like to see something purpose built to control brass shaving from flying everywhere. If these shavings get on the floor, and if you have a pet that might walk through it,. Well. Just imagine what might happen. Shaving sticks to pets paw(s), pet cleans paw(s), and inadvertently eats the shaving. So Ive made my own with a clear piece of plastic as seen in the photo I included. And the design of the trimmer works well with a U shape piece of plastic. If you need to control the shavings from flying, feel free to steel my idea. One other note, I recommend pulling the handle of the crank apart and putting some grease on it. It squeaks a bit.
Best trimmer on the market
This is without a question the best trimmer on the market. I typically use a giraud trimmer for my 223, 308 and 300 blackout when I don't care too much about the OAL (within 0.003"). I break this bad boy out when I expect extreme accuracy and it does not disappoint. I get 0.0005" (within the limit of my caliper) every single time.. Not almost every time, every single round. I am amazed how accurate this thing is. It's important to "hammer" each case in and out of the round holder to keep it from spinning, and of course make sure you don't have lube on it. If you do that, you can expect this trimmer to exceed your expectations. Only complaint is that everything is made of steel (not stainless) and it builds up surface rust over time. If you live in a remotely humid place you can expect it to surface rust (even if you leave it coated in Birchwood casey). Other than having to knock off the occational rust with a fine steel wool pad, I'm absolutely thrilled with this purchase.
Excellent value
I bought this after trying a Lyman and there is no comparison. I am reloading .223 and .243 rounds. The design of the Sinclair addresses all that is wrong with the Lyman, RCBS, Hornady, etc. The rail system and case holder utilized by the Sinclair is so superior for accurate and easy trimming that there is no comparison between the two. No need for pilot bits or trying t seat the casing perfectly (which is impossible with the Lyman and similar designs). Know that you will pay about "double" for the Sinclair/Wilson, but the job to be done is accurate, repeated case size trimming, right? Well, the Sinclair stainless ultimate trimmer is superior to the others and will not disappoint. I had to re-zero a few thousandths, but it was right on for me right out of the box.
Best trimmer I've ever used
Very impressed with the trimmer. The platform works well, and the calibration was perfect out of the box. I really like the logic of keeping the case rock solid whilst trimming. Very happy.
