one shooter in Ont.I know who won most of the shoots uses a shepherd 3-10 power withrange finding reticle adjustable fo specific trajectories..at that tme it was a600$ scope.An other fella I know uses a leupold 3-9 with special windage adj. if he guess the yardage at 37 yds he has a card wiyh him to show hoe many clicks to turn the elevation knob and he can hold dead on with 9 power mag.tough to beat these guys if they guess the yardages right.the excalibur scopes cannot compete with these customized scopes.

my take on the 3-D shooting scope is this. know your range mentally & the varizone will put you in the run. i use it on all of mine and do well in local 3-D shoots. its all about the right range estimation. then it boils on down to how well you can shoot.

scope
I,am one of the fellows that willy is talking about but he has it wrong . The scope is a leapol 2.5x7 major tournament by the rules OAA or IBO says you may not use a scope more than 7 power. Most clubs go by this rule just to stay in line with every thing and so they have no complaints about the power of a scope that someone is useing and some clubs don,t mind if it is a fun shoot. If you are planning to shoot a qualifier for the WORLDS AND TO SHOOT THE WORLDS IN NEW YORK STATEYOU MUST USE NO MORE THAN 8 POWER SCOPE.

The IBO has just released "new" crossbow rules again March 20, 2009, after publishing the rules January 2009. THe change cost me over $600 for a bow that is now not competitve, but was to the rules for January 2009.
Go to IBO.net, then to News, and read them for yourself.
The max power for scopes is 8x, if variable has to be taped or fixed by a range official at 8x or lower.
THe BIG change is a speed grouping and a minimum arrow weight for each speed grouping. How is a bow shooting 301 fps and a 425 gr arrow going to be competitve with one shooting 345 fps with a 450 gr arrow? Arrow weight minimums are totally absurd!
I emailed IBO yesterday, and will call them today to discuss my displeasrue with the change. Below is the email I sent them.
IBO just changed the crossbow rules, again! There was a rule change in January 2009. Then March 20, 2009 they changed them again! Now there are arrow weight minimums for speed classes! ( Go to IBO.net, and look under the "News" section for the "NEW" rules) The only thing I see with these "New" March rules is that it is now geared for the FAST bows. The slower bows are handicapped by having to shoot arrows heavy enough to slow them down disproportionately! I'll give one example. A bow shooting between 301 and 325 fps (say 303 fps as an Ibex will with 425 gr) is required to shoot a minimum 425 gr arrow. A bow shooting over 325 fps (say 345 fps as a Cyclone will with 450 gr) has to shoot a minium 450 gr arrow. Both of the bows mentioned lost 10 fps from my preferred arrow weight, but favors the faster bow. The difference in trajectory for the slower bow at 45 yds ( the max yardage) is 5.1". This forces the slower bow shooter be MUCH better at yardage estimation to score the same as the faster bow shooter, due to more drop. Let's not even consider the Stryke Force!
This greatly upset me as I just bought a new bow that fit the January rules perfectly, spent over a month tuning, and now I find myself behind the 8 ball! If I would be allowed to shoot an arrow that is deemed safe by the manufacturer, but less than the "New" IBO rules, I would still be behind, but only by about 2.5". The IBO has now "stacked" the playing field in favor of the faster bows. If this change had come about one month earlier, I would not have bought a new bow, but used my hunting setup.
I have emailed the IBO voicing my dissatisfaction with the rule changes. I have asked them to eliminate the arbitrary arrow weight minimums for bows shooting less than 325 fps, as long as manufacturer minimums are met. I am sure this will not happen, as the rule books are already printed! I thought the rules from January were not the best, but the March revision, absurd!

The person with the shepherd scope was Brad I. . He use to shoot excalibur till middleton swayed him . I used to shoot a scope with the target turrets as well with my card for the micrometer adjustments . When I was on I could guess yardages to within a yard or two ,just hold crosshairs on and let it rock .

Chris,
I new rules will allow you to shoot, but.....I don't see how you will be competitve! You probably won't get past the 325-330 fps barrier, thus forcing you to use a 450 gr arrow. Now compare that to a bow that is capable of shooting that same weight arrow at 345 fps. You are close, but the faster bow will allow the other shooter to be less accurate with yardage estimation and still score a ten. Let the Strike Force in and now that speed is going to be around 380 fps! As the IBO has always stated that the game should be more about yardage estimation than equipment, this change is in direct conflict with that goal.
I don't have a problem with eliminateing the max weight rule, but to then impose a minimum arrow weight is absurd! The lower weight bows are more affected by this as the weights listed are disproportionate. The new rules are definately geared to the faster bows. Adding 75 gr to arrow weight of a bow capable of 305 fps with a 350 gr arrow vs adding 25 gr to arrow for a bow capable of 355 fps with a 425 gr arrow is definately not in the best interest of the slower bow!
If the intent was to allow more bows into competion, then fine, eliminate the max weight, set a max speed limit for all bows that is resonable. Same as is now done with vertical bows.
I called IBO today and was unable to speak with anyone about this, but was told my email has been forwarded to the BOD. I was then asked to call back Monday to speak with the President of IBO to discuss this matter with him, after the BOD could assimilate my comments/concerns. I will do that!

Oh okay,so there was two people that shot that scope . Don`t remember a Doug from Forest city only Phil E. . There is a bunch of us that used to shoot but are inactive . Last shoot I went to a younger person was telling everyone how he was going to clean up because there was no good shooters there . What he failed to realise was that there was three of us from the old days that decided to get together . 
Boy was he mad when he came in 4th.

Final word from IBO
I talked to the President of IBO today. Ken called me and we had a nice disccussion. Unfortunately, he was not involved with the change in the crossbow rules. He suggested I repeat my concerns/comments to Terry Walters, the Director in charge of the change. Terry returned my call later in the day, and we also had a lengthy discussion. He explained his reasons for the change, and how it came to be. Terry did appreciate my view as well. Terry did answer all my other questions related to the wording within the rules to my sastifaction.
The bottom line is, the March 20, 2009 Rule Change will stand, at least for today. There are other things being considered, but until crossbow shooter numbers rise......
I think there are some real issues with the rules as written. Specifically the minimum arrow weights. Terry and Ken, both agreed that this specific ruling is disadvantageous to certain bows, but that it is the same for certain vertical bow shooters. Terry and I agreed to disagree on this point. It is easy to correct. We are to remember that this (the rules) is a "work in progress".
If more shooters is the goal, I don't see how this will help the cause. Yes more models of bows are now allowed, but I suspect the experienced "serious" shooter may opt for one of the "speed" models as there is a decided advantage. I'm sure the "newbies" to crossbow will also find the faster bows more appealing. As for me, I built up a half dozen of the required minimum weight arrows (for my speed class), and am considering selling/trading my "new" (6 week old) bow for a new Strykeforce.
It is nice to know though, that rules can be changed this quickly (within 3 months). There is still time to get it right before the Worlds.
