Calipers

[JagerDog]

I use Mitutoyo. The link is below. Aside from reloading, I also do machine work. I've used Mitutoyo for my machine work before I started reloading and just stuck with them. I've had the same caliper for over 20 years now. I also have a cheap one from Amazon that I keep in my desk as a backup. Probably used the cheap one twice out of the five years I've owned it. If I didn't already own a Mitutoyo I would probably buy a cheap one. They still get the job done.

I've never had an 8". Kinda rare IME. The 6" is $104 and I've seen 'em cheaper.

Sorry, mine is the 6". I did a quick Amazon search so OP can have a reference. I didn't read the description.

I have expensive ones both dial and digital. BUT I use the digital ones from Harbor Freight for my reloading and they work just fine

Yup! - same here...

Starrett, Brown & Sharpe, and Mitutoyo are recognized quality brands that I've used in aerospace manufacturing applications. Can't go wrong with them, but you'll pay the price. Without calibration/metrology to ensure accuracy, the next best thing you can look for is repeatability. If you can get ahold of some shim stock to use as a standard, you can get by with these"other" brands.

I've had Central Tool vernier caliper for a long long time and they've served me well. I know there's better out there or cheaper options that are just as good. But I have a tough time trusting digital or super cheap options. I'm just a middle of the road kind of guy.

I have a few different calipers... Mitutoyo absolute digitals, iGaging absolute digitals, cheap dials from Grafs, and cheap digitals also from Grafs. The cheap stuff is for teaching people reloading and when the the girl friend actually wants to roll her own. I mainly use the iGaging for my own reloading use unless I'm trying to be as precise as possible.

Honestly the iGaging are the best for the money. They feel good in the hand and are super smooth and repeatability/stability are as good as my Mitutoyo.

One downside to dial tools is when using them to verify trim length so shavings may end up in the rack. I don't want anything messing up a good set of dial calipers.

If you get a Harbor Freight caliper that eats batteries toss it in the trash. The batteries will cost you more than another caliper. I have left mine on for weeks at a time by mistake and you should get several years out of a single battery.

Mitutoyo for any real precision, Harbor Freight for less precise tuff.
