sitsinhedges Posted April 19, 2015 Report Share Posted April 19, 2015 I use the same scales. If they're playing up just bin them and buy a new set at that price. Quote Link to comment Share on other sites More sharing options...
10gaugewannabee Posted April 19, 2015 Report Share Posted April 19, 2015 same here use untill unwanted and then bin and buy again new, i have three small weights which i trial every so often to make sure they are close enough for my use Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted April 19, 2015 Report Share Posted April 19, 2015 (edited) Having looked at that link they are 0.1gram x 500 gram. For reloading powders you need a better resolution of 0.01gram. Nevertheless that type of scale in a finer resolution have proved to be accurate and very good value. http://www.ebay.co.uk/itm/300674919288?ssPageName=STRK:MESINDXX:IT&_trksid=p3984.m1436.l2649 Edited April 19, 2015 by sitsinhedges Quote Link to comment Share on other sites More sharing options...
oliver90owner Posted April 19, 2015 Report Share Posted April 19, 2015 (edited) I have the 10mg resolution version and it was less tha a fiver. The tare does not work, but I can get around that quite easily. Cheap and cheerful but accurate enough. I suspect they are likely sub-spec devices in one way or another. Might even just need a new cell. RAB Edited April 19, 2015 by oliver90owner Quote Link to comment Share on other sites More sharing options...

nicholiath Posted April 19, 2015 Author Report Share Posted April 19, 2015 No it does grains aswell Are you sure it only shows modes : g / oz / ozt / ct On description Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted April 19, 2015 Report Share Posted April 19, 2015 Are you sure it only shows modes : g / oz / ozt / ct On description Mine from there has 5 modes and includes Gn (grains) though I usually convert to grams for powder so I don't have to keep scrolling thru when I want to weigh a shot drop.

old man Posted April 20, 2015 Report Share Posted April 20, 2015 Sorry guys the accuracy of these cheapies can't be guaranteed, you need to verify with a reliable beam scale? Do some research on the net and see the cost of electronics with a certificate to verify accuracy? Always verify with a reliable beam balance?

oliver90owner Posted April 20, 2015 Report Share Posted April 20, 2015 Always verify with a reliable beam balance? I have checked mine with a set of standard masses. Not even bothered to get out my assay balance. It is not used for reloading, but is more than accurate enough for purpose. Quote Link to comment Share on other sites More sharing options...
johnphilip Posted April 20, 2015 Report Share Posted April 20, 2015 if they are just for reloading shot shells i think there fine Quote Link to comment Share on other sites More sharing options...
aris Posted April 20, 2015 Report Share Posted April 20, 2015 I have a set similar to this - they came with calibration weights. Basically an exact 200g lump of metal which you put the sale into calibration mode, stick the weights on, reset, then they are basically re-calibrated.

My cousin works in a lab where he has a digital scale which can measure 0.0001 of a gram. For fun we put some different pound coins on it - and the differences in weight were very noticeable. This kind of precision is probably OTT - but as you say - make sure you always use the same coin if using it as a check weight - you never know.

Of course you would use the same coin and write the weight upon it. Quote Link to comment Share on other sites More sharing options...

Bewsher500 Posted April 20, 2015 Report Share Posted April 20, 2015 you don't need a lab or a set of scales that weight to within +/- 0.1 of a GRAIN you will get more variation in MV from variance in neck tension and bullet variance than you will from counting kernels to get a perfect weight matched charge no factory ammo is ever charged by weight Hornady sell that same scale in the first link and it works great Overload slightly and allow scale to re-read and you can quickly work out which side of the 0.2grain tolerance it is smallest groups I ever got I only weighed every 4th or 5th charge, all the rest went straight into the case from a powder thrower!

oliver90owner Posted April 21, 2015 Report Share Posted April 21, 2015 Standard laboratory weights and it is a normal assay balance. I have used 6 figure balances in the past, so do know the difference between 'laboratory', assay, and semi micro. No, you most certainly don't need to measure to around the nearest 5mg, but I would never check the calibration/accuracy/precision of any scale with a lesser instrument.

Read my posts again? I checked with known masses. Last reply was to old man, who was suggesting that they should always be verified by a beam balance? I could have used my (admittedly old) assay balance, but I was quite satisfied with the standard weights and did not require the use of any of the rider masses. I am also aware that my old balance has 'age' and 'wear' issues, so I would not expect it to be as good as a newer item, but it will still be an order of improvement over my tiny five quid electronic chinese scale.

kimgary Posted April 21, 2015 Report Share Posted April 21, 2015 Having worked for Avery Berkel in the past I would like to say that modern digital scales are very accurate, \i use a small one from e-bay about £ 10.00 for measuring curing chemicals for home curing etc, mine reads to 2 decimal places. A handy scale checker is as follows:- 1p = 3.56 grams ---- 54.937 grains 2p = 7.12 grams -----109.875 grains 5p = 3.25 grams ----- 50.154 grains 10p = 6.5 grams ------- 100.308 grains 20p = 5.00 grams ------ 77.16 grains 50p =8.00 grams -------123.456 grains £1 = 9.5 grams --------- 146.604 grains £2 = 12.00 grams ------- 185.184 grains always check the calibration for your lowest weight to your highest weight that you are using to ensure the scale is linear. 1 gram = 15.432 grains so with a calculator you should be able to see how accurate they are.
