Thread: The Neil Jones Precision Measure revisited.

  1. #1

    The Neil Jones Precision Measure revisited.

    Last night I got to charging the 100, .223 cases I'd primed and prepped this past week. My normal measure is the Saeco Seeley Masker unit I've been using for the last 30 years but this time I revisited the Neil Jones Precision measure I'd been using during the Soap Creek Prairiedog Association shoot a couple of weeks ago. The can of H322 was already screwed into the measure and it should have been set for my 22 grain charge.

    A quick check with the Ohaus Dial-o-Grain showed it was still set for that charge so I started charging cases. For the hell of it, I weighed each fifth charge and was pleased to note so little variance in weight that is wasn't worth trying to record. Twenty-two charges weighed and there was no appreciable difference in any of them.

    The action on the Jones was needle bearing smooth. On only two charges did I get a (faint) sensation of a cut powder kernel and those two were also weighed and found to dead on. The smoothness of the action allows you to be very gentle charging; a nice contrast to the "smack it up, smack it down" action required of many other commercial measures.

    The micrometer adjustment is positive and repeatable -a feature that gained Jones his reputation. The precision of the build is such that thirty-seven clicks on my measure with H322 will deliver the very close to the same charge of H322 as thirty-seven clicks on any another Jones measure. BR shooters and builders will often refer to the charge of their load as X number of "clicks on a Jones"

    The last feature I like about the Jones is that you can screw the powder can directly into the measure so that it becomes it's own hopper. When you are finished loading, dismount the measure from the bench, invert it to pour the powder out of the mechanism and back into the can and you're done.

    As much as I like this measure I will admit that if I hadn't bought it at an estate sale for cheap I probably wouldn't own it. They sell for $500 US new, which seems expensive for a non-competition shooter, but when I look up on my shelf and see a Redding BR-3 "Precision Match" measure that won't hold .2 grains metering the same H322, and realize that worthless measure sells for $265 US, then the cost of the Jones doesn't seem too excessive.

    I'll be loading for 30-06, 308, and 6.5x55 soon. I'll let you know how the Jones works with the coarser powders. I'm not expecting anything great but we'll see. ~Muir

    Thanks for that, glad it has been working well for you. I would be interested to hear how it fares with H4350 or perhaps H4831sc in the .30-06...

    As it turned out I was loading some light-ish 30-06 loads for my daughter today and used 47 grains of H-4895. The Jones hit either dead on or +/- .1 grains on the dozen or so I weighed. I think that shows great promise.~Muir

    (I should go try it on 4350 this afternoon.... I'll get back to you.)

    Ok. I got curious and dumped 10 charges of H4350. I had scant little left and my only other tubs of 4350 were unopened as of yet so I just kept dumping the powder back into the Jones-provided hopper.

    With the measure set at my 4895 settings of this morning, 10 charges of H4350.

    45.5 grns
    45.4 grns
    45.6 grns
    45.5 grns
    45.7 grns
    45.6 grns
    45.4 grns
    45.5 grns
    45.5 grns
    45.6 grns

    Averages don't much matter in this instance and standard deviation would be meaningless on such a small sample, I think. Still, not bad: plus or minus .1 grains and a little bit.~Muir

    PS: I should add that on the Dial o Grain Ohaus it is possible to discern a part of a tenth of a grain. If it was above 45.5 grains I rounded up, if it was below I rounded down. The 45.7 was actually 45.6 and a little bit. Not quite to 45.7 grains.

    IS he still alive ?

    Seems he passed some time in the late 90's !

    I first heard of him thru some of Ken Waters articles .

    Yeah, he is one of the old timers. I have one of his measures. It's quite good but the Jones is better with the coarser stuff.~Muir

    It is, isn't it? Frankly, I was really surprised at the accuracy with H4350. Trickling charges may be a thing of the past.~Muir

    Look at those huge variations, it's rubbish, send it to me I'll pay the postage can't bear to see you wasting your time and effort on this sort of kit
