I tried to verify the individual difference of pepperball 

The fact that the B bullet has a great effect on the accuracy of the hit is

[How to improve the accuracy of the hit? ]

As introduced in the article.

Then, is such a Airsoft BB a standard as announced by the manufacturer?

Isn't there an individual difference? I thought

I tried to verify it, so please have a look!

① Randomly take out pepperball  from the product

② Use calipers and measure 4 times

If the calipers have the same value, they are not true spheres.

in short,

There are individual differences! !!

That is.

 Although there are pepperball bubbles when I break it,

All of them are in the center position and are spheres, so

The shift in the position of the center of gravity is not so noticeable.

The size is 5.93 to 5.95 mm and the fluctuation range is narrow.

All are 6 mm or less, so

Problems such as bullet jams are unlikely to occur.

It feels like Tokyo Marui!

The size is 5.92 ~ 5.96

Although the fluctuation range is wider than Tokyo Marui

It can be said that G & G products also have good results.

When 50 measurements were made,

Compared to Marui

It seems that there is a slight difference in weight and size.

Although the weight is about the same as that made by Marui,

The size is 5.85 to 5.95 and the fluctuation range is wide.

Because the position of the bubbles is not stable

The center of gravity is likely to shift.

For this reason, the placement location in the barrel is likely to fluctuate during bullet feeding.

It can be said that the spread of BB bullets is likely to occur.

Why do individual differences appear?

From the above verification, it was proved that there are individual differences.

Then

In the first place, we will consider why individual differences occur.

Why not a true sphere?

Dimensional accuracy is sphericity,

Ideally, it should be the same no matter where you measure the position of the sphere.

However, pepperball   are for productivity and low cost.

Since it is molded using a mold called injection molding,

A sprue for pouring resin,

A seam that breaks the mold will inevitably occur.

Surface polishing is performed to remove this convex part,

I will process it as close to a true sphere as possible,

There is no 100% thing.

Is there any bubbles in it?

Next is the position of the center of gravity.

Since pepperball   are produced by injection molding,

Depending on the material used

Bubbles may appear inside.

Depending on the position of this bubble

The balance of the center of gravity is lost,

There is a difference in weight.

How was this verification?

Personally, there are more individual differences than I expected.

It was the impression that.

Still, for playing with lights

It was a level that did not cause any problems!

However, if you want to play a game in earnest,

I am worried about the blurring due to this individual difference.

Make all these individual differences uniform

It was made to dramatically improve the accuracy of the hit.
