Pellet scales

[panman3]

Hi all,

Can anyone recommend an accurate & reliable pellet weigher please?

Thankyou

I have tried a few, On Balance (no pun intended) CT-250 Carat Scale work well for me and were not very expensive.
I imagine a simple google will bring them up for you.

try the local cheapo shop that stock tobacco tin, herb grinders and oversize rizzla`s, the usually stock small scales that can weigh pellets, probably not extremely accurate but OK for comparing pellets or just sorting into weight groups

Doesn't it say the pellet weight on the tin?

Seriously though what percentage of 8 grains do you hope to measure either side of the manufactureer stated weight? You will surely need laboratory standard scales.

The weight on the tin is about accurate as the head size on the tin!

I don't know what a laboratory standard scale is but, the ones suggested above measure accurately (and repeatably) to 0.001g which should be good enough for even the most fastidious sorter of pellets

That should do it!

Guys I too used to laugh quietly at people who weigh their pellets, wash them lube them etc.etc. Admittedly, I will never do this on an ongoing basis for my needs but I did do it once and was shocked at what I found.

After fitting an Altaros regulator to my S200, I was keen to find out just how consistent it made my power output. I therefore decided to eliminate any variables by weighing and grading just 100 pellets for my test. Now according to the label on the AA Diabolo Field tin, 8.4 Grains is 0.547 grammes. According to the converter on Google, it should be 0.544 Grammes !!! Already a discrepancy. Well, I cleaned them and then started to weigh them ... arranging them neatly in stacks of .02 Gramme intervals. The resulting picture was a near perfect but shallow Normal Distribution curve with the minimum weight of a pellet coming in at 0.490 grammes while the heaviest pellet was a whopping 0.620 grammes !!!!

So assuming my regulated S200 was putting out a perfectly consistent speed of 780 feet/second, the resultant spread in foot pounds energy would vary between 10.22 ft.lbs for the .490 gramme pellet to an illegal 12.93 ft.lbs for the heavier .620 gramme pellet. The resulting variation in POI at say ... 40 yards does not even bear thinking about. Or in other words, if the power is consisten (which it would be with a well regulated rifle) the speed and therefore the POI will shift dramatically with a standard un-sorted box of pellets. Makes you realize why they grade it when you are seriously into winning competitions and matches.

I was under the impression that pellets are formed from lead shot. To manufacture the lead shot, molten lead is dripped through a sieve like structure and the "drips" fall into a water bath as spheres. This cannot possibly give an accurate, consistent shape and weight.
Therefore, the manufacturer cannot, and understandably, won't measure and adjust each blank.
Also, even the moulds used for Aston Martin pressed fibreglass wings differ in thickness and profile. So pellet moulds? Believe it, they're going to vary.
Now, if you still believe that Aston Martin hand beat pure aluminium into body panels, and they don't use hot pressed glass fibre, come to Crewe and I will show you the line. It's only 7 miles away and anybody can walk in!

lead shot for shotguns and fishing is produced from gravity towers that way, but pellets are chopped from coils of lead wire then stamped in dies so they are as accurate as 5p coins coins.

I asked H&N if they made to 4.51 or if they made to 4.5 then sorted with laser measures into batches by size. I reckon I am right but they insist they can coin them to exact size, however nobody mentioned weight to the same accuracy.
