Madbull Precision 0.20g Tracer review

Madbull precision 0.20g tracer 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 it was nicely constructed, no visible seams were on it and was not polished as much as the precision ammo but was shiny still. Leaving the ammo in the light for a few minute then going into a dark room these glow well and fairly bright, overall in the bag there was no giraffes, no contaminants and the ammo had no waxy coating like some of the heavier weight precision bb’s.

Rifle test:

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

Magazine used was a sniper 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, until the hop dropped off at about 40/50meters.

Next I tested there consistency on a target at 25meters. The same magazine was used. The groupings achieved for 5 initial shots were 15” from the standing unsupported position. The following 5 shots were 10” in the semi supported kneeling position. On full auto a grouping of 20” was achieved, the majority of the shots were within 10” but the few flyers went out to 20” , No rounds missed the target.

Consistency testing:

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

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

here are the results:

5.91mm

5.94mm

5.92mm
Range is from 5.90mm to 5.94 which is a variance of 0.04mm

so the bb’s are 5.92 +/- 0.02mm

There were no miss-shaped bb in the pack of 1000 rounds; they are all polished with no contaminants.

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 19.60g

so that’s an average of 0.1960g per bb.

Conclusion:

These overall performed better than the 0.20g precision bb’s, there much better constructed and the difference in noticed in the accuracy tests. Also the consistencies of the diameters are a lot better. Only let down on these was the weight was slightly under 0.20g’s per bb. If the weight was slightly better these would be a good choice of tracer ammo. For the price I would recommend them but mix them 10:1 ratio with normal bb’s for tracer fire.

Rating:

Quality 8/10

Accuracy 8/10

Price 8/10

Consistency 8.5/10
