"Accuracy is fantastic for .25g , they fly true and straight. Any curving is do to hop-up/bucking/nub problems.
I have numerous quality AEGs and GBBs and these BBs made it clear which had good Hop-up units and which did not.
I have found BBs on my yard in the midst of dissolving and have discovered that once the anti-friction coating dissolves the BBs are clearly 2 halves joined together. but the halves have their edge rounded so the seam is edgeless.
Which is irrelevant since the anti-friction coating makes them perfectly spherical and seamless.
UNFORTUNATELY, unlike the .20gm BBs which out of the 5K where nearly if not all "FLAWLESS"
THESE bbs had plenty of defect ones, mostly discoloring but also a few imperfect ones as well as one that almost looked like a "SPIKED BALL"! Imagine if one as such where to slip into a 6.01 tightbore barrel or a Teflon or anodized coated barrel??!!
I think i'm going to stick to the more expensive Biovals for my .25gm and up BB needs.
