ok, i just ordered a APS2-SV from airsoft extreme with the 250% upgrade plan. i didn't think about this when i ordered but.... it says it will shoot 450fps with .25's. if frostee has a 200% and his shoots like 510 i think he said with.20's then that will mean mine will more than likely shoot over 550fps with .20's right? but i plan on bringing this gun to op: firebrand so 550 is the limit on sniper rifles, so i was wondering if anyone could verify that it will shoot over 550fps so i can order a 200% spring and get that in time. thanks a lot fo your help in advance.

There's really no way to tell if its going to shoot over 550fps, because every replica fires differently even with similar upgrades. However, based on my experiences you should order the 200%.
Last year, using my APS I recorded the speed of different weight bb's and I saw an average 35 fps increase with every .05gram drop in weight. Your actual results may vary, but using my method you can guess that a 250% spring firing .25's at 510fps is going to at least put .20's out at 545fps which is too close to the max for error. If you want to guarantee that you're going to come in under 550 fps it would be best to stick with the 200%.
