oooh ok that makes sense. So how far are your tanakas currently shooting accurately?
The stock one? Probably 250ft, maybe a bit further. The upgraded one? At it's prime, I'd say about 330ft, maybe 350ft. Needs a new bucking right now though. I'm working on a review of the Bell M700 (Tanaka clone) that you might want to check out as it has some interesting discoveries about the Bell. It's got a lot of the typical Chinese poor QC in it, but they also did a few things right. As in better than the post ban Tanaka's.
Sorry, I think you have a pretty bad sense of distance. 250ft? No... Not with the hopup design that comes with the Tanaka. But if you can show me in person or in a video where they are 250ft man accurate, please do...
Just out of curiosity, how far do you think your magical KJW will hit someone at?
Edit: I can't access YouTube at work, so I'll look some more when I get home but most of the reviews I see for Tanaka M700's also state they were able to hit a man sized target in stock form at 225-250ft.
In its current form in a pile of crap? Well it won't..
Airsofter reviews are crap, because most airsofters a bunch of idiots with little sense of distance and generally full of crap. 300-350ft shots are obtainable, but just not something you can do with money and a little time. You really need to invest some serious cash..and even then, you are lobbing a tiny little bb and if you even hit someone at that range they are probably not going to feel it or call it.
My rule of thumb is that range is limited to the flat trajectory the hop up produces, so if you can "hit" something at 300ft but 50ft of that is hop up lobbing up then down, that really isn't real range.
I've seen 99/100 videos on youtube of people shooting the Tanaka's and other guns, trust me, none of those guys were hitting 225-250 accurately out of the box. It just doesn't happen with that gun.
