Single pin long range is off

Hi all,

I have been using an HHA single pin for years with no issues. Recently, I bought a new bow and with it, an new HHA Tetra Rze which I love.

I sighted the bow in precisely at 20 yards, being able to leave the set up tape on zero as is preferred.

Then I took my time and got tight groups at 60 yards which gave me sight tape 32 which is quite fast/short.

When I shot it anywhere between 20 and 60 at random numbers, it was on.

This bow, an Elite Omnia 65# is shooting my light 385gr. Gold Tips at 305-307fps. 85gr field points.

So here's my question:

When I shot the bow at a laser ranged 81 yards, all 5 arrows were about a foot or two low. They were directly under the paper plate, but low. Windage good, elevation off.

Now, my hypothesis is this. Since these arrows are super light and fast, they bleed energy fast past 60 yards and drop off since they don't have the kinetic energy to keep going.

*I also used the same range finder for all ranges so it's not an issue of different range finders giving different ranges.

I wanted to ask you why a bow/sight that is dead on at 60 yards in, is shooting low at 80+ ranges. I'm sure at 100 it would be even more pronounced.

Any easy fix by cranking it down to 86 yards for the true 81 yard distance, but what do you think?

Thanks.

Did you sight it in with the range finder? If so may be looking low in peep at the 814 yard position. Don't take much at the longer distances.

I sighted in with a range finder. One thing I just thought of based on your comment. My 3/16 peep is not super precise on this sight housing. It's a little bit too large. I wonder if a next size smaller peep would be better? The thing was all the arrows were relatively together, but low. I may be looking low in the peep like you said.

Thanks. I'll keep it in mind and make sure it's centered in my peep. I may have to go down a peep size too. This bow belonged to a hunter before me and I think getting more light in for shorter ranges was his intended purpose.

It may not be ideal for 80-100 yards shots.

I do as the above mentioned. I use a pieces of masking tape and mark my own marks after I have perfected that range. Then match tape to my own made tape. I haven’t done a ton of shooting past 60z I just don’t shoot that far. Being alittle older I’m not consistently accurate way out there. I have plonked a few here and there

At 305 fps the sight scale is pretty compressed at close distance where you may think is exactly on but its hard to tell if it truly is exactly on at close range… as you get further out in distance the gap opens up and this is where being off 1 yard or 2 is much easier to notice… are you using a bullseye to sight in or a horizontal line? I shoot at piece of black electrical tape to set my sight tape… try this at 30 and 60 yards to pick a sight tape

Some tips I’ve learned over the last few year shooting out to 150 yards that really help. Set your peep height with your sight at about 60-70 yards. When you shoot farther it with help with the long range anchor. Might feel a touch cramped at shorter ranges but nothing crazy. Get an adjustable peep and find the perfect ring as close as possible. Any variance will hurt at long range. The 20-60 is not the perfect tape and you won’t always keep that. Mine changed 3 tapes down from 47 to 44 after shooting in my 100 yard mark. All the detail above are great ideas, using custom tapes with marks, helps get you Dialed in. Remember that the tapes they send are from one arrow setup that you likely don’t have. The variables at distance are going to change from setup to setup. I’ve had the MBG sights as well and they do sometimes match but I always made mine in archers advantage and dialed in up to 120 yards my using a caliper…not easy but doable. It’s a great sight choice I love my RYZ max and my wife has the RYZ. Let us know how you make out!

When I set up the sight, initially, I set it all the way forward since that is best for accuracy from what I've heard. Then, I had to move it all the way in to match the peep as close as possible.

Also, my set up tape started at 0 for my 20 yard and ended up at 32 for my 60 yard. The sight provided additional set up tapes. I can just take one and see which sight tape it matches closest to. I imagine this is the same as making my own 20-60 yard initial measurement tape.

I know it's not a perfect system. I could have chosen sight tape 32 or 33. I felt my 32 was a bit tighter so I chose that.

100% it's micro adjusting your anchor point (that you may not be aware of) with the scope being below your peep like mentioned above.

One thing that I learned from a John Dudley tip that I never thought of....this is more effective with a handheld release. At longer range once you are anchored, gradually open your mouth/jaw which lowers your lower jaw line and minutely lowers your perceived anchor point and helps center your peep on a lower scope position.

It works pretty slick!

On a slightly different note, let me ask you all this.

Since I don't hunt, I've always tried to keep my arrows as light as possible for speed. Gold Tip Velocity 300's with 85 gr. field tips = 385gr. (29" CTC)

Can I do better if I upped the tips to 100gr.? Taking into consideration longer range energy retention. It's only still be around a 400gr. arrow.

Will that small of a change provide better long range performance or should I leave it alone?

Your sight tapes are based on an equation... the information used in that equation has to be perfect to get perfect results...

1) Most shooters could set their bow to 17yds and still stay comfortably in the white on a blue face at 20. (there's a 3yard difference right there). Then, when you get to 60 yards, your pin/dot/reference takes up more real estate on the target... with a .019" pin that could be a 3-4yd margin of error just based on your pin size at that distance.

2) For best results and a sight tape... Shoot a sight mark for every 10 yards and match it up to one of the tapes in your kit. then go to the furthest distance you KNOW you can shoot good groups but probably won't smash arrows... Shoot at that distance and reset your indicator.

I've had this issue before on pre-printed sight tapes.

The longer you can sight the better. I usually use 20 and 80 or even 100. I'll put a blank piece of paper on the sight, get sighted in at 20, mark it, then start walking back slowly until I'm shooting dead on groups at 80, 90, 100. Mark that on my sight tape.

Then I go back and use my calipers to measure the distance between my 20 and long range mark. I take that measurement over to the sight tapes and match it up.

I've had much less issue doing it this way than using their math to figure it out.
