Scott Parker's scale tuning method

golfer2b2000 said:
I understand the importance of throwing a perfect powder charge for the best accuracy. But I go to the supershoot and watch these old shooters throw from a thrower like a harrels, or a sinclair, and go out and produce some of the tightest groups imaginable. I think their shooting ability goes far beyond being able to throw the "perfect" charge. I am sure that his scales are great, but if I am to become a good shooter, I think this is not the place to start. I think I would make sure my setup is good, my shells are consistant, my breathing and tension in my body is at a low. These guys I see shoot amaze me by their accuracy. But they throw directly from a thrower, and I know that the throwers can't be as accurate as a highly tuned scale..

Going out on a limb here and say that you don't shoot long range. The loading techniques that work for short range don't apply to long range.

I agree with what you say here for short range shooting but I believe this post refers to use of more accurate weighing methods with long range shooting in mind!
 
That may be true. What I am saying is before I am going to be worried about throwing a charge over or under by .002, I best think my efforts or concentration should be more in my set up, etc. The differences between short and long range although differ, basics remain the same...

Long range shooters typically preload. They tend to pick a condition and then run their groups. In long range benchrest they cannot see their shots as they shoot their group. In short range very few events have been won preloaded. Typically shooters load between individual matches and adjust their loads based on their targets and changes in ambient conditions. Over the course of a two day event, typically there are 20 individual matches. They can see their shots as they are fired, and may choose to wait for a condition to return, or run the group, or parts of a group based on the vast array of wind flags on the range. During a match, they can shoot unlimited sighters. Also, there is absolutely no need for the kind of powder charge accuracy that is routinely sought for long range.
 
Scale Instructions:

Use the check weight value to set the level of the scale. After moving the main poise, depress the pan with your finger and let the beam swing a few times. This allows the washer on the right side of the poise to find the bottom of the V-notch. Throw charges about 1/2 grain light and trickle up each time. This will yield the most consistent charges.

I studied chemistry and I totally understand why he fiddles with scales :)
When I was buying a scale for reloading I couldn't settle on anything above 1mg accuracy, I was acctually thinking of buying analytical scale but couldn't justify the costs at thet time :-[

Agreed! I work in plant breeding research, and some of my time is spent in the genetics lab. 1mg accuracy was my limit as well. You can pick up some older Mettler scales for a couple hundred bucks on ebay and then calibrate them. Just keep in mind that Mettler does not support anything more than 20 years old. Mine is 36 years old, and I'm having to manufacture parts for it.
 
Send scott a ohaus scale 1/19 for repairs , plus check .E-mails and phone not returned. Check was cashed .Two years no scale! Beware this is who you deal with!

If I read this correctly you have been waiting TWO YEARS??
It appears this post is from 02/24/2021 about 45 minutes ago. Maybe I read this wrong.
 
Something fishy going on. Have you contacted him recently?

I sent Scott a scale a couple weeks ago and he phoned me soon afterwards with the bad news that my scale had a magnetic hot spot and can't be calibrated. So as soon as he has a new scale calibrated, he'll ship it and my old scale to me. I would expect the entire turn around time to be about a month at most.

PM me if you need a contact phone number for Scott.
 
As a beam scale user I am curious to know how would I know if my scale needs to have calibration? I use an electronic dispenser & the beam scale reads the same as the electronic scale.
So...

Durn good question. I don't have a definite answer, but would like to.
 
I shipped a vintage Ohaus 10-0-5 scale to Mr. Parker last autumn after prompt up-front communication, and I specifically asked about turnaround time, received 2-3 weeks as a response.

UPS tracking confirmed delivery 10/22/2020. On 11/11/2020 I sent an inquiry regarding progress as 2 weeks had elapsed, no response other than my checks (one for labor & one for return shipping) posted to my checking account shortly afterwards. I sent additional inquiries on progress the following dates with no response: 11/14, 11/20. I sent another inquiry12/03, this time I received a response Mr. Parker was sick with COVID-19 but would have my scale finished that weekend.

I gave him the holiday season off, sending another inquiry 1/11/2021 with no response. I sent additional inquiry 1/18 saying at minimum I deserved a sitrep, received a response that a return shipping tracking number would be sent to me the following day. However it was 1/21 before I was sent a return shipping tracking number. That number showed USPS actually received my scale on 1/23, and it was delivered back to me 1/26.

Go into shipping a scale for service with eyes open and don't expect much in the way of return communication once you actually ship a scale, based on my experience, which seeing other posters, was far from unique.

The "Freshly Tuned Ohaus 10-0-5" he posted on is business Facebook page might have been the 10-0-5 I sent for service, described above.
