All markers should be limited to lower than 300 fps ideally 280-290.
So range should be about the same,Apex tips do add a bit of range as they apply backspin.
Accuracy comes with consistency ,i.e. the marker fires the same amount of gas each time, also the bottle's reg supply's the correct pressure.
Then your onto ball size/ barrel match, then onto the quality of the paint.
So in a nut shell decent speedball marker, that's serviced,with a good barrel match, firing quality round, seam free paint us as good as you are going to get.
Then its down to you,as you are firing the thing.
Practice practice practice and have fun whilst doing it.
