Madbull Precision 0.20g review

Madbull precision 0.20g BB’s

Supplier:

The BB’s were supplied directly from Madbull themselves; these were in small 1000 round sample packs.

Packaging and shipping:

Item came well wrapped in a sturdy cardboard box, inside were the 13 sample packs with the extra space padded with packaging. Item was sent express and was delivered by Parcel Force.

First Impressions:

My 1st impression of the bb’s were that they looked well made, opened the packet and removed a bb’s it was nicely polished, no contaminants on the round, Unfortunately though, the one I picked out had a massive seam line across the middle, at first I thought it was just an visual embedded mark but running my nail over it proved otherwise.

Rifle test:

Test rifle was an standard internals Star SL8 firing 320fps with 0.20g BB’s,

Magazine used was a Star mid capacity magazine; the sample bb’s were loaded into the magazine with a speed loader. The first magazine all bb’s went straight as a laser line (but never to the same place), until the hop dropped off at about 40meters.

Next I tested there consistency on a target at 25meters. The same magazine was used. The groupings achieved for 5 initial shots were none on target and a spread of about 2ft and then the following 5 shots were exactly the same spread. On fully auto 1 out of 10 shots hit the target.

Consistency testing:

I’ve tested a random sample of  the Madbull 0.20g precision bb’s

random batch of 1000 rounds supplied from Madbull, random 100 bb’s from packet (bought in April 2009)

here are the results:

5.97mm

5.95mm

5.91mm

5.94mm

5.92mm

Range is from 5.91mm to 5.97 which is a variance of 0.06mm

so the bb’s are 5.94 +/- 0.03mm

and only one 5.97mm came up so that could been a problem with the callipers.

There were no miss-shaped bb’s in the pack of 1000 rounds, they are all polished but 30% have seam lines which were about 0.5mm deep but there were no proud seem lines

I then did a weight test of another random batch with the results as follows
I used a grain scales but they kept fluctuating on grain due to not having a flat surface

so I put 100 bb’s on that were dry and not humid from being handled.

I got 20.25g

so that’s an average of 0.2025 g per bb.

Conclusion:

In conclusion these 0.2g bb’s are not good quality. There poorly made, not very precise and don’t hit the target accurately. Out of all the bb’s I have used these rate in the lowest of the, Even Cyma sample bb’s are better consistencies than these.

Rating:

Quality 5/10

Accuracy 2/10

Price 2/10

Consistency 5/10
