In my opinion, range and accuracy are and always will be more important that simply being able to get a load of shots downrange. Simple reason being, that if I can hit someone from further away than they can hit me, then I'll always have the option to fall back when I'm under fire, far enough to be out of their range but for them to still be within mine.
First things I do are fit a tightbore barrel, preferably a 6.01mm, upgrade the hop if required and then, once those things have been added, I get my gun shooting as close to the site limit as possible through any combination of things, get it to shoot as consistently as possible with as little fps deviation as possible, then equip it with .25g BBs and job's a goodun'.
365fps on a .2 - roughly 330fps with a .25, combined with the accuracy of the tight bore and best hop set up possible, set to provide the best range possible and I can comfortably hit people with 5 shots or less at up to 45m. Often it only takes 1 shot at standard AEG engagement ranges. Even in woodland scenarios.
And that's a proper, measured 45m. It's a lot further than you think. Longest range hit I've had must be somewhere in the region of 70m, but it took around 20 shots or more and I had to aim about 6 feet above the target.
