How fast are you shooting your current set up? In order to effectively shoot dead flat to 30 yards, you need about 330 fps. I had my Vulcan set at 70#/30" shooting a 390 grain arrow at 315 fps. I had the same idea of setting 1 pin out to 30 yards and it is possible, but it takes a little guess work. I set the pin dead on at 25 yards and was only 2" high at 20 yards and about 3 inches low at 30. I could hold dead center out to 30 and make an effective shot....however, if you set your second pin at 40, this creates a hole as you have a 15 yard variance between deadon 1st pin and 2nd pin. I opted to go with a heavier Axis FMJ arrow grained out to 450 and shoot it 297. This is a heck of lot more energy and a lot more accurate. When you get upwards of 310 to 330 fps, it's amazing how erratic your bow will shoot if it is not tuned dead nuts and if you arent used to shooting that fast. Please dont let this discourage you from more speed, you may be an excellent archer or have the time to practice enough to get good. But if you are shooting in the 280's, chances are you may not get up to the 310's without a lighter arrow and upping your pounds to 70. Just speaking from my own experience.
