Madbull Precision 0.43g review

Madbull precision 0.43g 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, No visible seam lines, and appears to be no odd shapes in the packet.

These bb’s are black in colour, this makes them near impossible to see, and harder to zero the scope in with, But make them excellent for invisible shooting (i.e. no visible round for the enemy to see where it came from). Rubbing the BB against a piece of paper left a black waxy line and an impression on the BB. I found the black bb’s to leave the worst of these lines on the paper. This coating wears off in your hop chamber leaving a residue which starts to affect the accuracy.

Rifle test:

Test rifle was an Upgraded Tokyo Marui CP2 VSR firing 525fps with 0.20g BB’s, 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 65 meters.

Next I tested there consistency on a target at 25meters. The same magazine was used. The groupings achieved for 5 initial shots were 2” with 1 outside in the 4” grouping. The following 5 shots were 4” from the supported position

40 meter test the accuracy was still consistent at 5” with a few outside but all would have hit a head size target at 40 meters.

Consistency testing:

I’ve tested a random sample of  the Madbull 0.43g 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:

5.91mm

5.91mm

5.91mm

5.92mm

Range is from 5.89mm to 5.96 which is a variance of 0.07mm

so the bb’s are 5.925 +/- 0.035mm

There were no miss-shaped bb’s in the pack of 1000 rounds, they are all polished and 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 42.20g

so that’s an average of 0.4220 g per bb.

Conclusion:

These performed better than I thought, I had to have my hop full on to use these with any good range. These should ideally be used with rifles with excellent hop (the vsr needs a better hop arm for this ammo to be used to it’s full potential). For the price, if you have a 550+fps rifle these are perfect for you and being black make it near on impossible for the enemy to see. But light shining off them enables you to set the hop and zero the scope still.

I also advise unless you’re going to clean your hop every time you finish firing these, to avoid them as they leave a residue on your hop and barrel.
