Accuracy

Dumbazz, this is all fixable we just need to figure out exactly what is going wrong.

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 had similar results as grabeard,only I used everything that came with the right stuff package.I have my speed dial set at 325.

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!!

Thanks for the extra information.

There is a VERY SIMPLE step to take to determine if it's your scope that's defective.


You say that when you use the 40 yard pin on the 40 yard target it shoots LOW. That means that the trajectory is not as flat as you have set your scope to shoot. You have dialed in your speed setting for too fast a bolt speed. Using only one bolt, the same bolt, shoot again, but with a slightly slower bolt speed setting.

That SHOULD cause the bolt to impact higher at 40 yards. Keep on adjusting, using that same bolt. Keep doing it till it's on target at 40 yards.

DON"T FUDGE AROUND WITH THE ELEVATION DIAL TILL YOU HAVE IT HITTING THE TARGET AT 40 YARDS. Don't fudge with it then either.

Now, test to 50 yard pin at 50 yards and the 30 yard pin at 30 yards. If the scope is not defective and you have used the same bolt, you should be on target at thos ranges. If not, it's likely your scope.

I have tried using the same bolt over and over as you mentioned, just to see if I could get it set up right.

It seems that adjusting the speed ring has no affect at all.

20 yard crosshair fine.
30 yard chevron fine.

I have tried the speed setting from between 275 and about 310, with no difference at all.

Brent, look through the scope when you turn the speed ring. That ring is a zoom ring, you should be able to see it zooming in and out as you turn the dial. If it changes than it's time to move on to the next idea, if it doesn't zoom then we have found the problem.

Are you merely saying that adjusting the speed ring makes no difference at 20 and 30 yards? Have you actually tested at 40 as well and there is no difference in point of impact there as well?

That is critical.

Since you have repeatedly used the same bolt for your tests, we can rule out bolt variation as your problem.

If you followed my suggestion of shooting at 40 yards, and there is no change to point of impact when you dial in a slower bolt speed, your scope has to be the problem. You need to shoot at 40 yards. At 20 and 30 yards it won't make a huge difference what you dial in for bolt speed.

Depending on how accurately you shoot, at 20- 30 yards you might not notice a difference when you adjust bolt speed, especially if there is only a subtle difference in where the bolts hit. That's what it likely would be.

Good Luck.

Just got done testing the Slick Tricks and the Wasps . . .here is what I found.

Both flew erractically using a straight fletching. Sometimes a bolt would just dip like crazy just prior to impact and land 8" low at 30 yards. However, most were within 5" at 30 yards and within 3" at 20 yards.

Using the 4 degree offset . . .both gave me 2" groups up to 40 yards. I did not test 50 yards . . .ran out of time. However, the way they were flying, I feel fairly confident they would still group well at 50.

I also tested lining up the fletching with the blades with the Wasps. This didn't really have much effect either way. I tried lining the Slick Tricks in the 3,6,9, and 12 positions and again, not a lot of difference. The big difference was the off-set.

All yardages were verified with my Nikon rangefinder. I used the same 4 bolts that were pre-shot with field tips and were shooting "lights-out" up to 50 yards prior to testing the broadheads. I did not "zero in the scope" for the switch from field points to broadheads. However, I did test the scope to insure accuracy with field tips prior to the test. Also, the grouping information was how close they came to my aiming point, not just their groups . . .a real measure to "shooting like field points".

Based on this testing . . .the 4 degree-off set is the key. I'm not sure how the Right-stuff Package is set as far as off-set goes. Dumbazz . . .do you know the degree off-set of your fletching?

I think I may have to get together with the old fart and fix the problem myself.

[Dumbazz]

I think it I have it fixed!!! Scope don't work!!!!!

Old fart??? Oh Tye, and I even said I would put a deer in front of you so you could pop your cherry!!!

New scope on the way. Can't wait to test it.

A big thanks to everyone, especially Pydpiper!!!

Cheers,

You know I was only joking.

[Dumbazz]

No deer for you!!!

[TYE]

No deer for you!!!

I shall get my deer. If I don't get one with the rifle.

[Dumbazz]

A rifle????? Will you be wearing a skirt as well??
