I'd be very interested to see your source material proving for FACT that the autococker is any more "accurate" with the same paint, barrel, and velocity. Because according to studies by WARPIG.com and Action Pursuit Games magazine, there was absolutely no difference in "accuracy" between open and closed bolt markers (by the way, that's a referrence to how the BOLT operates, NOT the air system. Since the autococker can use any preset or adjustable air system, that's not a good argument to prove it's accuracy) from a set firing distance with both markers bench-mounted using the same paint, barrel and same velocity. So, what it comes down to is your paint, your barrel, and your velocity. It's been said and proven a million times, but I'll say it again: A ball traveling at 290 fps coming from a Spyder will go the same distance, and hit just as hard as a ball traveling 290 fps coming from an Angel. You can talk about perceived accuracy and recoil all day long (evidently if your marker has any recoil, and you're too feable to hold onto it while you're shooting, that will throw off your "accuracy"
) but if they're both set to the same velocity, an autococker and a bushmaster are going to be just as accurate. So throw accuracy out the window when considering your decision. Incidently, I don't remember which came first, the bushy or the Impluse (I think it was the bushmaster, but not 100%), but it's (the bushy's) design, IMO, is alot more well thought out than the impulse. Not to mention I'd buy ICD over Smart Parts any day based purely on principle.
