calipers

Well, unless you're measuring Glocked brass, because as all high-class reloaders know, Glocks are inferior. Mwaaaahahahaha (j/k)

You know, I was having FTF about 10-20% of the time in my 40 and couldn't figure it out until I checked the diameter all the way around and found the 'glock bulge' in a good number of them. I push all range pickup 40 through the RCBS tool and have no more FTF's. Doesn't seem to be a problem in the 9mm, probably as the case has more taper than the 40 IIRC.

and yes, even my digital caliper picked up the bulges.

Hehehe. Good thing you found the issue. So far my Sigs and HK don't mind the bulge after minimal resizing.

Yeah, it was a bugger. I was checking and adjusting the powder, changing mags, all to no avail. Then I sorted the cases for 'bulges' and the %ages were spot on. Started with a sort for non-bulged cases and voila - problem solved. Ordered the RCBS push-through die set the next day.

My 40 is a Springfield XD and it does NOT like bulged brass.

Digital has more resolution only because the markings are so far apart on a dial caliper.
People that use a dial caliper understand that you can read MUCH better resolution from a dial caliper than digitals though because you can see the analog needle is sitting between the marks.
Even though I don't trust any of them for accuracy less than a couple thousandths (I own micrometers for that), a dial caliper will show you 0.0001" where digitals are 0.0005" at best.

I think you mant analog.

From a metrology standpoint they are equivalent. Best practice allows only 1 "eyeball" division.

But as you infer, the discreet measurement is sometimes less important than seeing "wiggles" in the needle. Those 'wiggles" aren't available in digitals with 1/2 digit in the 0.000X position.

Oh it matters plenty. It may seem pompous and/or dogmatic from where you're sitting and enjoying your popcorn. However, knowledge has been called to task here and nobody likes to be wrong! Hehehe.

Well, you obviously don't know my history here with recommending that people get a decent pair of Mitutoyos and getting tar and feathered for saying such.

The fact is that reloading doesn't require great accuracy, so the best calipers are not needed. I just don't like using a crappy pair of HF calipers that smell like 2 week old Chinese food.

There's also a history of people dropping names of people using and recommending HF calipers as to why everyone should use them.

It matters not to me, I say, use whatever floats your boat. For me it's a decent set of calipers, I probably have at least half a dozen (analog and digital), so I have my own self covered!

Yeah that is unfortunate. You should always recommend the highest quality or the red equipment...

But taking a brief pause for a moment. Why would anyone need a precise set of calipers that can measure a **** hair on a frog and how would they get training in how to use them because I can always make my calipers show smaller by pushing too hard in a direction... :\

I hate all calipers because of that, I think that if I had precision calipers like the ones you are ARF Barrels talk about, I would just be that much more inaccurate because I am untrained in how to use or get a TRUE and accurate reading out of them.

I do not like that my General will show 0.0000 and then when I squeeze them a tad they show -0.0005 GOD that is annoying, but nothing moved...

Mostly because a good set of calipers is not only about accuracy, it's about operation and use. The mechanism, slide, control, and if digital there is also battery life. Cheap calipers just feel cheap to me, and in most cases if left on will run that batteries into the dirt. A decent set of Mitutoyos doesn't exhibit this battery problem, will feel much nicer in use, and be plenty accurate. If true accuracy was needed, get a micrometer.

It amazes me how this topic always comes up here. Obviously calipers are useful in reloading. It also amazes me that people consider $100 to be an expensive tool.

I have a pair of fairly inexpensive Chinese calipers with a remote display that gets a feed through a proprietary wireless protocol. A friend developed it, but the couldn't bring the cost of manufacturing down, and the patent department didn't grant him a patent on it, so he gave up on the idea. His firmware turns the caliper off quickly so that battery is not a problem in the caliper or remote display. The remote has about 3/4" numbers, making it easy to read. Nice to use on a mill or lathe.

My calipers ratchet/clutch so the same pressure is applied each time no matter how hard I push. See the pic I posted earlier.

Not true.
When you squeeze harder, you are bending the beam and the slide can close up more.
Calipers definitely take proper skill to use accurately.

How often do you see analog calipers advertised or referred to?
Analog is inferred when talking about dial calipers.

I have never seen a digitial dial caliper.

There are dial calipers.
There are digital calipers.
You can substitute analog for dial if you prefer.

You might want to re-read your post. Analog/dial. The body of your text doesn't jive with the initial statement. That's all I was saying.

[ar15barrels]

The body of your text doesn't jive with the initial statement.

The first line was in response to someone elses statement that digital calipers read to 0.0005" while dial calipers only read to 0.0010".

If someone is so dumb that they can't "read between the lines" on a dial caliper, then perhaps the statement is true...

THERE IS NO MORE ANALOG! WE ALL SWITCHED OVER TO DIGITAL A YEAR OR TWO AGO! REMEMBER? The GOVMENT GAVE US A WEBSITE THAT WE COULD GRAB TWO DIGITAL CONVERTER BOX VOUCHERS FOR $99 ???

HELLO?

Come on folks, let's get with current times here.

Now THAT is cool. Wonder how much they cost if he made them as they were... Would be nice to have it set to give a readout of each of your ammos before they drop off the ramp from the press...


(yeah I said that.) :D

Oh the Rolls Royce's of calipers debate. This is why I buy good stuff and not so called high end trendy stuff that you read about on calguns and other cool forums. Remember how easy life was when there was no internet.

Please do not remind me.

I will say one thing though, at least the porn has gotten better...
