Any improvement Dumbazz?

What bothers me is that it is high at 50 but low at 40.

You have ruled out the bolts as defective, so either the distances are not accurate or else the scope is defective.

I think what is missing here is that the chevrons are there as a reference .If we were all shooting the exact same setups then the marks could be made exact BUT I shoot 2219`s,someone else shoots carbons.The trajectories of the two arrows shot at the same speed will be different do to the kinetic energy .But on a side note I get the bow close at 20 then go out to 50 adjust for windage because it alot more noticable.Then adjust for up and down for I already have the speed ring set from putting it through a crono .This is how I set up all my target bows for accuracy for it was not the 20 yard shot that was off a .250 inch that sank you but the 54 yarder.Hope this helped a little, if not the deer haven`t complained yet about your bow being off a little.

As long as he is not mixing different types of bolts, ie bolt weight and type of fletching, once he has set the speed ring appropriately, even at varying distances bolts should strike consistently high or consistently low. Also, it doesn't make sense that it strikes HIGH at 50 and LOW at 40.

That's why I think that it has to be either a wrong distance measurement or else the scope is defective.

Defective or loose.

The chevrons should be exact. Once an arrow is matched to the scope the chevrons should be exact, like Hi5 says though, everything must be consistant first.

[quote="Hi5"]What bothers me is that it is high at 50 but low at 40.

The 50 yd. point on the scope was used at 40 yds. that's why they were high.Why they were so low at 40 yds. using the 40 yd. pin, I guess we had to be there.

Good Heavens. I have such a terrible headcold that my head feels as though it's stuffed with wool. Man, it's a good thing SOMEBODY reads what is actually contained in a post.

I guess I can forgive myself, though, for not expecting questions about what may be "wrong" when the questioner knowingly uses the wrong chevron for the distance to the target!

If you re read my post, you will understand what I did. Because the 40 yard chevron was so low at 40, I decided to try the 50 yard chevron at that range to see where it impacted. And it impacted high.

Ranges are from a laser range finder and paced off the same. My normal stride is 1 yard.

Scope, mount, etc is all tight.

Using four different bolts, (all the same) and 2 different broadheads, (both the same), I had the same problem.

Twenty yards is dialed in and groups very tight.

I am beginning to think that there must be an issue with the scope.

Think I am going to switch back to field points and start from scratch again. My broadhead target is pretty much shot to crap now!!

PS... I did not shoot at 50 yards for fear of missing the target completely.

Here's what you need to do. Start over - set your speed ring to about 280 - there's no way you'll get 300 with a Phoenix with 2216s.

Number your arrows.

Now sight in at 20 with the crosshairs as accurately as you can. Make sure you take at least 20 shots, off a bench rest, in calm conditions, and center the whole group pattern. A tight group of a couple of arrows is nice, but you need to shoot a lot of arrows and center the WHOLE group - not just your best few shots.

If you have any arrows that consistently don't group, check to make sure it's not the same numbered arrow each time.

Then go back to 50 and use the 50 mark. If you're on, then everything should be OK. If you're low, adjust the ring slower, and if you're high, adjust it faster. Again, you need to shoot a lot of arrows, and center the whole group.

If after that you find you have problems at 40 or 30, then it's time to consider a possibly defective scope. But that's highly unlikely.

Hmmm... at 20 yards I can put them in the same hole.

then at 40 yards I can do this...

I'm thinking something is wrong with the scope.

Still not getting anywhere close to the accuracy as many have described here. Wrecked 2 more bolts and broadheads today in the process.

Looks like I have a 20-30 yard xbow. Gonna call Excal tomorrow.

I never really plan on shooting past 30 anyways, and never shot at that range initially. I recently decided to try a few longer shots and that is when all this started.

At this point in time, I have no confidence in the scope at all. Would rather a single crosshair low power scope and just know where it shoots at different ranges.

I have no problem admitting that I am far from a very good shot. But I fired close to 50 shots today and still cannot get this dialed in. I have a good solid rest.

Is there any chance that I should go to different broadheads. I orginally started with 3 bladed 100 gr Muzzy's and had problems. Then went to 3 bladed 100 gr Wasp Boss's, and still having problems. But not to the same extent as the Muzzy's.

When I originally sited in field tips to the Boss's, I had to adjust a good couple inches both ways.

All the problems I am having are elevation, the left/right is fine.

Strange. I find the Wasp's to be the most accurate for me.

I think something must be wrong with the scope. Talk to Peter or Bill T. and I'm sure they'll fix you up.

Maybe I did mine wrong, but I set the speed ring at 350 and sighted in at 20 yards. That's all I had to do. 30, 40, and 50 yards shoot 2.5 inch groups. I was shooting 100gr muzzy practice points. Sounds like you have a scope issue.

I'm going thru the same issues. The Max shoots perfectly with field tips. At 30 yards with fixed head broadheads, I can see the bolt dip 6-8" just prior to impact. With mechanicals, I'm pretty much dead on.

I'm getting ready to turn my blades on my Slick Tricks to where they are at 12, 3, 6, and 9 o'clock per Bob's instructions and see how that helps. Not sure how you would help the Wasps. Maybe align the blades with the vanes.

I think I'm going to try some Simmons Innerlocs and NAP Spitfires.

The only other thing I can think of . . .have you checked your yardages with a rangefinder? It doesn't take much of a miss in yardage to make you think you are off at 40 yards.
