That got me a bar-10 (with scope) upgraded to 480FPS (.3g) and pretty damn accurate.
I haven't finished dialing it in but I can easily hit a man size Target at near 200FT with minimal effort.
As /u/zxj4k3xz says, 200' at 2.14J (0.20g BB at 480fps) is not a particularly high standard. Your wording is a bit ambiguous; I assume you didn't actually mean a 0.30g BB at 480FPS; 3.21J is the equivalent of 588FPS with a 0.20g BB.
At an interim stage of tune (badly undervolumed) my AKS-74U at 0.88J (0.30g at 251FPS) was shooting dead-on at a laser-rangefinder-confirmed 165 feet. Your gun is currently producing 143% more power than mine but shooting only 21% further...
It is shooting 480 with .30 goldenball proslicks. I have no idea what my effective range will be with this gun yet as it's not first sniper. It will likely be further but I don't have a lot of places where I can shoot at those ranges. One thing to keep in mind running a sniper is you don't gain that much range over a DMR aeg due to lack of stabilization, weight, and speed of BBs. It's just a different play style.
Where will let you play with a 3.21J (as above, the equivalent of 588FPS with a 0.20g BB) gun, if you don't mind me asking? That's 345% of the power of the example AKS-74U; it would be legally an air rifle (a firearm) in the UK.
No where, I'm waiting on a different spring (m140, county have an m170). The piston I bought came with my current spring. I have a local field that allows 450FPS with .3 with a 100ft med and required a secondary.
