I have a small bottle of these things, it came with my L96. They really perform no differently to plastic BB's of similar weight and quality. It actually performs pretty good, partially because my gun seems to like .29g weighted BBs most, so .30 is quite good. outperforms KSC perfect .25 in terms of flight path, but nowhere near as good as .29 SGMs. Slightly nicer flight path than a Digicon .36 on my gun.
The only thing is they seem quite soft, so they're prone to small nicks and damage, more so than plastic BBs. Because of this, they tend to jam in 6.01 barrels...
The impact seems significantly less so than .36 digicons as CDN_stalker suggested from last time I played with them.
I have 2 personalities, Telkin and Valcrow.
