For someone more experienced than I am.

When I shoot 200 grain grizzly broadheads on woodies spined anywhere from 65# to 95#, they dip right before impacting the target. I say dip, but there may be a more descriptive word for it. The grizzlys are the ONLY head that make my arrows do this.

When I shoot 190 grain Ribteks from the same bows with the same arrows, they fly straight to target. Why the difference?

I have not tried this beyond 20 yards by the way. Consistently does this under 20 yards.

Correction. Woodies spined anywhere from 65 to 105.

I'm thinking that the dip is the tail kicking up on impact, possibly because it may be flying tail up before impact.

My other thought, is that the sight picture between the broad heads is enough of a difference to affect your aim.

I think it's the former. The arrow must be flying nose low and impacting the target kicking up the tail. My question is why does this NOT happen with a 190 grain head??

Have you spin tested it, just a little bit out of balance can make a difference.

You don't say what your bow weight is, or arrow length, or string type, or center shot capability. All those things may have something to tell us.

The Grizzly may be longer than the Ribtek as well as 10 grains heavier. To me it's likely a spine issue.

Are the heads orientated the same on the shaft? Change shooting distance 3 yards to see if still does it. Target material could also be affecting impact.

Grizzlys usually have superior flight out of any Bow, like darts thing for me.Shalom

The heads are not oriented in any particular way

I made them for my hill based on some research with other shafts and point weights. Thought they’d fly perfectly.

They don’t!

Grrrrrrr!!!!

So change them until they do. If you are right handed and the go right, then as George suggested it's likely spine. Add a little material to the sight window to move the point of the arrow. Then shoot them some more.

If that doesn't do it, then you either have an aiming or mounting issue with them.

Are the bevel of the broadhead and wing of the feathers matched? Could a left bevel/right-wing setup (or vice-versa) affect the arrow’s recovery from paradox?

What plenty coups said.

Two 2¢ thoughts:

Do the Grizzly broadhead arrows have about the same FOC as do the Ribtek arrows?

At 20 -25 yards, do the Grizzly broadhead arrows group with your field point arrows?

Left bevel heads are matched with left wing feathers yes

Turn the broadheads and try again. Sometimes on 2 blades it makes a diference. Blades horitontal vs vertical.

Ok

I’ll try turning them

Thanks

My guess is neither broadhead is tuned. Nobody can tell the difference between 190 and 200.

You mention spines from 60 to 105. You'll never tune an arrow with that range.

Mount all you're broadheads horizontal. Start another thread if you want me to explain why. The answer is a rare case, but could happen, add wind and you might have a problem.

What you need to do is shoot a couple of field points and then a couple of broadheads of equal weight. If the BH is high, move the NP down and vice versa (it'll probably be low)

If BH is left of FP and you're right hande ithe arrow is stiff. If you don't know what to do with stiff or weak read www.fenderarchery.com/blogs/archery-info/basic-tuning. The broadhead part is towards the end.

The spine of your arrow is off. Google nock left arrow flight and you'll find with nock left arrow flight, broadheads will always impact to the right.

I thought I had my bow and arrow setup tuned perfect. Then went to tune the broadheads. There was a kick to the broadheads like you described. I adjusted the nock point, I mean slightly, and it went away. Im betting like Plenty Coups said, adjust your nock point for the Grizzlys.

Thanks all. I’ll try these pointers.

Have someone watch arrow flight looking over your shoulder. What you see is often different from what they see.

Sent you a pm Justin

Any wind you were shooting in. BH up or sideways is a consideration.

Need someone to watch is a valid point.

All arrows fly in a parabolic flight. They do not fly nose low or nose high, but they can kick around and fly like a drunk log. Did you mention your draw length and bow weight? Arrow length?

Arrow flies well after turning the broadhead.

I have always held to the opinion that broadhead flight problems is a arrow tuning problem, or broadhead not mounted straight.

Some broadheads are more forgiving of slight errors than others. As a rule the bigger the broadhead the more critical arrow tuning becomes.

everyone has their own way of tuning, a lot of info is a take off from compound bow tuning.

Anymore I tune with broadheads right off the bat pretty often, getting field points and broadheads to fly the same.

I never paper tune...I never worry to much about nock left, nock right ect....I pay closer attention to point of impact.

i'll bare shaft tune carbons and aluminums, woodies I always tune with fletched broadheads and field points together.

I would shoot more than one broadhead just to make sure that was the problem, and I'd darn sure shoot them farther than 15 yds or so. A well tuned arrow will fly true whether its 10 yds or 50 yds.

I’m tuning for broadheads. It’s possible that they are misaligned slightly but I’ll be checking on that.
