i came up with -.04 at 10yds,.00 at 25yds,-4.38 at 40 so sorry if not being an inch and a half i was proly holding high I only tried it while I was sighting in at 40 still that is very flat

That's generally the case! People hold high and don't even realize it.

I'd still bet your arrow will drop more than 4.38" from 25yards to 40 yards. 4.38" is almost 3 times the drop you 1st claimed. You're getting closer.:wink:

I've shot lots of different combinations at higher speeds. Like I said even at over 400fps you can't say that it hardly drops any because even at those speeds it drops a considerable amount.:cool:

I like speed but an arrow still drops even out of a fast bow. That's the reason I use a rangefinder.:happy0001:

I took the calculations of the archery program withthe full details of my set up i don't think it gets mor accurate than that unless you are in the factory tuning it threw machines

Z7 is getting reviews that it is the best bow Mathews has ever put out, since the Switchback in 04 0r 05 when it came out.

I realize there are variables that may affect these charts but they will not vary by a very big percentage. These are pretty much inline with my hands on experience as well. These should make for interesting reading.

1. Start by shooting a group with your bow at a target from 20 yards using your 20 yard pin.
2. Mark the center of your group.
3. Next, shoot from 40 yards , still using your 20 yard pin and aiming at the same point on the target as before.
4. Mark the center of this group.
5. Finally, measure the distance between the two marks.
6.Refer to the numbers below for your arrow speed.
Approximate Arrow Speed (fps) Spread between 20 & 40 yard groups (inches)


Just how fast would you have to shoot to drop just 6"?

check out "the archery program" it is abviously more in depththan the progam u use.That figure you put up is way to cheesy. Put in your figures and see for yourself

If you want more solid proof download "the archery program" put a mathews DXT signle cam then a monster XLR8 duel cam in with all the same set ups arrows shooting the same # and fps there is more than 2 inches differance drop at 20 yds 12 more ftlbs of KE, 30fps volocity.you tell me there is not a differance when using cheap charts.check this for yourself before you post against me again.

I don't need any other programs. My post was made from hands on experience the figures I posted (from 3 different sources) were for your and others benefit. If you think all those are off by 200 or 300%. Fine!

Just don't expect me to believe it. I've shot a bow or 2 in 41 years and many of those years was spent shooting a 1 pin nonadjustable sight where knowing your arrow trajectory was of the utmost importance to success.

Have a Great Day!:happy0001:

The Monster 7 is tack driver. Awesome bow!!!

i am sorry you feel that way but these programs i am reffering to are dead on. If you want a real true program you need to check these out. this is as advanced as they come. just becouse 2 bows shoot the same fps and draw wieght and arrow does not mean they will have the same drop. I am not trying to offend you it is just fact
