Pistol measure

[cfullgraf]

So the drop isn't case-activated.

The Redding powder measures can be modified to work with Hornady's or RCBS's case activated powder measure system.

The discharge has to be tapped to accept the drop tube from the case activated kit and a new actuation lever needs to be fabricated.

I prefer the Hornady's system better than the RCBS unit but the difference is small. Note, the Hornady cast activated system is a clone or license built unit of the RCBS unit. I use my modified Redding 10-X on the Hornady L-N-L and an RCBS Pro2000. Soon, it will also be used on a Dillon BL550 once I get the stand finished for the press.

Walkalong's solution is impressive. It appears that his design does not alter the powder measure.

I use it on the LNL. I set it up to drop automatically, but it will also work with the Hornady or RCBS linkage set up as well.

Wow that is a cool solution. Like when members think outside the box

That's true, but it'll be festive and in season come December.

I've been using the RCBS Uniflow for 40 years and find it works great for handgun loads. I've also sort of lusted after the micrometer version, but after reading some of the comments, not so much anymore.

Once I work up to the perfect powder drop, I use my caliper to measure the length of the adjustment rod that's sticking out and record it in my log. Then when I need to return to the setting for that specific load, I use the caliper to get the adjustment rod back into that area and fine tune it using the scale. It works pretty well for me and is quicker than just guestimating the area and fine tuning.

Festive is nice!

Like the idea of tracking measure data with calipers. That I will have to try

if you can find one, the Ohaus DuoMeasure has both

the rifle and pistol cavities in one drum. You just move a set screw from one hole to another to switch from the rifle cavity to the pistol cavity.

Now owned by RCBS, the DuoMeasure is very similar to the Uniflow, just easier to use and switch. I have a Uniflow, a Redding and the Duo and it's by far my favorite.

Lots of people just have 2 Uniflows, one with each drum. I keep 2 Lee primer tools for that reason, I just don't like switching the stems.

There's a nice looking Duo on feebay right now

Looks promising. Never heard of that one before is that a discontinued product or still in production?

Someone had mentioned a CH product in a previous post. Their website shows a push button powder measure. However the information is very limited and no bushing information is given. I have emailed the company for more info.

long discontinued but very well made. typical Ohaus quality.

Mine has a replacement lid and when the hopper finally breaks, it looks like a bottle off of a Mec shotgun press will fit.

The Redding powder measures can be modified .... I use my modified Redding 10-X on the Hornady L-N-L and an RCBS Pro2000. Soon, it will also be used on a Dillon...

I like the design of the 10-X. Now to try to find one at a reasonable price...

.....

Fabrication of the mod is excellent ~ simplicity & function

The little RCBS "Little Dandy" is a joy to use if you don't insist on absolute versatility. and under $40 at Midway.

 

[javelinablanco]

If I cannot find a good priced pacific with bushings I think I have narrowed it down to either the RCBS dandy or the push button CH. RCBS is well documented but little info exists on the CH.

Hornady LNL Pistol Micrometer Metering Insert



Found one in my reloading tool chest I forgot I had. There was a pistol rotor assembly in there too. Have two LNL powder measures BTW.

I was wondering if there was a way to get a ballpark setting for a particular powder load.
First thing I noticed was the dial was not zeroed.
Fully inserting the micrometer stem locked it to the rotor against the powder measure housing. I backed off the stem until it could move, loosened the lock screw of the numbered thimble and set it to the zero line on the stem. Very few flakes of titegroup powder managed to get into the rotor and did not register on my electronic scale and balance scale.

Then I removed it from the pistol rotor and measured the diameter of the piston, 7.92mm = 0.792cm.
Next was to measure the stem
Measuring stem at at line numbers 1, 2, 3, 4 gave a stem length difference of 2.56mm± = 0.256cm per number.
There is another line in between the line numbers which is 0.5 value, which is equal to a full rotation of the thimble.

So Cylinder Volume per full number =∏ x Radius Squared x Height. in cm
0.12612cc = 3.142 x (0.396 x 0.396) x 0.256

My Electronic scale just wouldn't settle down.
Had to resort to balance scale.

Good news.
Hornady's Pistol Micrometer Metering Insert is very consistent on powder throws, surprisingly so.
Talking .1gr accuracy with titegroup on RCBS balance scale up to highest weight I measured at 7.3grs (.32S&W Long case)

As for using the micrometer for accurate powder weights, yes to a point.

Using Lee's VMD #( Volume Mass Density) for Titegroup of .08475 and the CC volume number I derived from measuring the Hornady Micrometer of 0.12612cc per whole number on the stem, it was very accurate to what it should have been up to #3.0 on the stem.

It should have been 4.46grs by calculation and it came out 4.3grs on three consecutive throws. Still not too shabby.

At #0.2 on the stem it should have been 0.297gr. and I got 0.3gr.
At #0.3 on the stem it should have been 0.446gr and I got 0.45gr.
At #0.6 on the stem it should have been 0.893gr and I got 0.9gr.
At #0.7 on the stem it should have been 1.04grs and I got 1.0grs.
At #0.8 on the stem it should have been 1.19gr. and I got 1.5grs.
At #1.4 on the stem it should have been 2.08grs and I got 2.1grs.
At #2.0 on the stem it should have been 2.97grs and I got 3.0grs.
At #2.7 on the stem it should have been 4.02grs and I got 4.0grs.
At #2.8 on the stem it should have been 4.17grs and I got 4.1grs.
At #3.0 on the stem it should have been 4.46grs and I got 4.3grs.
At #4.0 on the stem it should have been 5.95grs and I got 5.4grs.
At #5.0 on the stem it should have been 7.44grs and I got 6.7grs.
At #6.0 on the stem it should have been 8.93grs and I got 7.3grs

Actual VMD's may vary as much as 15% from published numbers with different lot number and my Volume number for the stem of 0.12612 maybe be off also. My Titegroup lot was 1072307(1lb July 23, 2007) next line 160 actual lot #

Expected calculated weight was done by ( Micrometer stem # multiplied by 0.12612, my cc volume per full number on stem ) divided by Lee's VMD # for Titegroup .08475 to get expected charge in grs.
Error does grow with volume.

Still very useful. No powder drops were larger than expected within scale tolerances.
Now to get some 2.0gr loads for 32 S&W long done up.

I like the RCBS Uniflow. About the same price as the Lyman #55. In the ~$80 range.

It takes some patient fiddling to get the desired weight just right, but once you tighten it down it stays good, consistent and reliable. I have lusted over the available micrometer stem for it, but have never been able to justify it at nearly $50.

^^^ +1.

The optional baffle (or one you make yourself) helps with some powders, like 700x.
