RCBS Chargemaster SAJSV artikel, Jaco Brink

Dagsê manne
Ek wil my RCBS Chargemaster 1500 se spoed verbeter deur aan die settings te krap.
Jaco Brink het mos destyds 'n netjiese artikel geskryf op die SA Jagters forum spesifiek hiervoor, maar ek kry dit glad nie.
Kan iemand dalk help?
Gewaardeer.

Kyk op Youtube, Erik Cortina het n video gemaak waar hy die settings verander het.

Ek het dit so gedoen en dit werk baie lekker!

Dankie, ek het daardie artikel gesien, maar soos ek verstaan is die waardes tussen hakies die default waardes, en nie Jaco se aanbevelings nie?

Ek het hierdie gedoen met my chargemasters:

This has made a tremendous difference in my reloading experience with this scale. The scale is fully adjustable and there are many settings and that you can change. To enter the program mode press EDIT MEM and ENTER at the same time. After making an adjustment press ENTER to go to the next option. After the last setting the scale will reset and countdown. If you passed a setting you have to start from the beginning, there is no back button.

This is the list of settings that you can make to your scale, for some of the functions I do not have detailed instructions as to what they do, and would recommend that you do not change them:

HSB_A1 (15.68) Grains under target weight to go from full to high speed for low weight
HSB_B1 (3.42) Grains under target weight to go from high to slow speed low weight
BSP_C1 (1.08) Grains under target weight to go from slow to final trickle speed low weight

MSP_A2 (39.20) Grains under target weight to go from full to high speed for medium weight
MSP_B2 (8.55) Grains under target weight to go from high to slow speed medium weight
MSP_C2 (2.25) Grains under target weight to go from slow to final trickle speed medium weight

SSP_A3 (196.00) Grains under target weight to go from full to high speed for heavy weight

SSP_B3 (42.75) Grains under target weight to go from high to slow speed heavy weight
SSP_C3 (11.32) Grains under target weight to go from slow to final trickle speed heavy weight

SEL (065)
F_A (050) Grains for a Heavy Charge
M_A (035) Grains for a Medium charge
S_A (006) Grains for a slow charge
W_F (200) Rotation for Full speed (200 Means 20gr)
W_M (100) Rotation for Medium speed (100 Means 10gr)
W_S (036) Rotation for slowest speed (036 means 3.6gr)

S_F (012) Scale sensitivity timeout time in m/s fast speed
S_M (024) Scale sensitivity timeout time in m/s medium speed
S_S (128) Scale sensitivity timeout time in m/s slow speed.

“S_” parameters control the dwell time for measurements at the different speeds and a setting of “64” corresponds to 2 seconds (each unit being 1/32 second). When you increase these values you will note a longer lag time in detecting the scale reading and adjusting the trickle speed. I assume that this will allow the scale measurement a longer time to settle when running at the slower speeds.

A large setting for “S_F” parameters will cause overcharges.

I have to advise you to only make changes to your scale if you are confident to do so, and remember that there is not a “return to default” setting in the scale. If all else fails return your scale to the default settings listed above in brackets.
I am now able to throw 56 grains of S365 in less than 18 seconds (average of 15 charges), and with very few overthrows.

Another problem I experienced with the scale was that there were continued overthrows. The RCBS employee advised me to take a McDonnell's straw (because it is thicker than a normal straw), cut off about a half inch piece and put it into the tube where the powder exits. This caused the last part of an extruded powder to clutter less, and reduced the amount of overthrows dramatically.

Also something that helped. I lifted the pan of the scale closer to the tube. This decreased the time of travel since the powder exit’s the tube and falls into the pan. The scale can only measure material in the pan. This also seemed to decrease overthrows on the trickle speed. To do this I used a piece of neoprene self-adhesive strip on the bottom of the pan.

I hope you have more joy a with your scale now

Jammer, ek sien dit is maar wat op daardie Safari link is

Ek het nou deur my Chargemaster gegaan en dit was my settings

Is die default setting ?

Post by **Geno** » Sat Oct 14, 2023 8:40 pm

Ek weet nie of dit default of wat is nie. Dalk het hul later die settings daarna verander in die fabriek. My 2de chargemaster (ouer as my eerste een) was baie stadig toe verander ek dit na daardie nommers toe loop hy saam 'n ander een wat ek het wat lekker vinnig gooi.

Die waardes tussen hankies is die fabrieks default waardes.
Ek gaan Erik Cortina se aanbevelings op Youtube gebruik.

Laat weet asb hoe dit werk vir jou. Dalk is albei my skale nou op default en is ek nie beter/vinniger gewoond nie

kettieklip · Post by **kettieklip** » Wed Nov 01, 2023 11:44 am

Geno, Erik Cortina se aanbevole waardes maak definitief 'n verskil.
Ek vind egter dat dit nie noodwendig goed werk met alle dryfmiddels nie. Dis so maklik om waardes te verander, ek doen dit nou vir elke dryfmidderl.
Is mos maar net die eerste drie parameters waaraan jy krap.

Dankie, ek kyk daarna!
