ASR accuracy

I headed out yesterday to do a little zeroing in with my ASR, and was not exited about the accuracy I got. First up, here is a list of parts/ modifications I have done:

Echo 1 Upgrade Kit
Mad-bull Version 2 509mm 6.03 barrel
PDI 96 hop up
Guarder bucking with dental floss insuring tight fit
Six barrel spacers
Polished and slightly widened cylinder head as per here:
Teflon taped cylinder head, and piston head screw

I shot from 100 feet using .25's at a torso sized target, and while I could hit the target every time, there where no good groups to speak of. I then moved the target out to 240 feet, and had no consistency at all, any hits were pure luck.Also, while the time it took the BB to hit the target at 100 feet was roughly one second, the time at 240 was incredibly long. I had time to lift my head from the scope, and count to 3 before hearing the hit. Seems like the fps are slowing down a lot, but my gun is shooting hot (550fps).

I'm getting .3's and .4's soon, I'm assuming this will help?Any suggestions/comment would be appreciated!

I have not chronoed using a real chronograph, only using a soda can, the "poor mans" chronograph. It punched through the bottom as well as the top of a soda can, putting it around 550 fps.
So I did a compression test, holding my finger over the barrel and dry firing. I heard air hissing out after the shot was fired. It seemed to be coming from the hop up area, but I am 99% sure the hop up to barrel to bucking connection is good, but I suppose the nozzle to bucking connection could be bad.

Peyote, thanks for the information! This is what I had hoped would happen as far as a heaver BB.Though slower at the beginning, it retains its speed longer.

Newbie, yes unfortunately Mad-Bull is the best I can do at the moment. Eventually I want to get a PDI 6.08 and an R-hop...but that's another topic ;)

wyvernfist, no I haven't "polished" it yet.I have swabbed it with normal gun cleaning patches, but I was under the impression the the Version 2 barrels were not supposed to be polished. It seems to have a almost glassy finish in the interior. I was a little afraid to polish it up.
Could be. Do you remember if it was a smaller inside diameter or outsider diameter? I'll take some calipers to it and see.
