Im new to crossbows and i was wondering if you had a fixed scope with one crosshair and sighted it in at 30 yards. How much would it be high at 20 and how low would it be at 40 yards and so on. How much does lets say 305 fps vs. 365 fps bolt differ at these yardages.

Thanks

365 fps is going to shoot flatter longer distance than the 305fps.Get out the range finder and just start slinging arrows down range to figure out what ya can do.At 305 you would think 20 and 30 should be pretty much the same?Mine was easy to sight in scope Im shooting 380fps and its flat out to 40yrds.

The only problem with Excal ,Hawke and others is that those test are done on their Xbows.Bobby you just have to hit a range and see what your own setup can do!! Every Xbow is different. You can take 2 Xbows with the same poundage same arrow and they both will shoot differently.what also helped me was I video taped my shooting to see what was going on with arrow at different ranges.This is just my opinion Bobby :)

You will see by the charts that an arrow will drop approx. three feet at 50 yards @ 300 fps. When you see the claims of marksman hitting 2 inch groups @ 100 yards, think of arrow dropping approx. 7 to 8 feet. This gives you an idea of the skill or imagination of the shooter.!!!!

Here is another video that I think helps demonstrate what a crossbow will do at given yardages.

At Parkerbows.com you can download their Redhot ADC program and all you have to do is know your bolt speed and it does the rest.

Check out the Tips section on Horton's website. They have a good graphic that shows arrow drop that I believe is factored at 300fps.
