I decided to test what .25g BBs will work better out of Matrix .25g, GoldenBall .25g, and washed GoldenBall .25g BBs. I was the GoldenBalls using Soccer77's method.

I usually use matrix .25g BBs but I had been reading more and more about what BBs you use and what affect they have on your guns performance. My gun, a Custom M4, is shooting about 370fps with .20g. My hop-up set up is a Modify Hop-up Chamber, Systema bucking, Element H-nub, and a Prometheus ash 363mm barrel.

I had one midcap of each loaded and I was testing in my backyard. Its about 225ft long. There is a tree dead smack in the middle about 160ft out. That will be my target.

The Gun and Mags


The mags. You cant see it very well, but they are labeled.


My range. The tree in indicated in red.


Results:

The Matrix BBs had about a 3ft spread with lots of flyers. About 1/3 of the BBs went 3 more ft left or right.

Both mags with GoldenBalls yielded the same results. About a 2ft spread at 160ft with no flyers at all. I actually think the unwashed ones might have had a little tighter groupings than the washed ones, which surprised me.

I now need to buy a crap-ton of GoldenBall BBs. Lol. After this experiment, I don't know why I was using the Matrix BBs.

If anybody has any questions, feel free to ask.
