So the goal for my shooting session today was to take advantage of my 3-Pin Black Gold Pro Sight and put a sight tape on it (even though I’m not going to shoot a deer past 30-35)...I just wanted to stretch it out to 60-70 today for fun...my shooting sessions usually consist of multiple rounds at 15, 20, 25, 30, 40, some Kentucky windage shots at 50 using my 40 yard pin and finish with a round at 20-25...

so today I started at 40, made sure all was kosher...went to 50, turned my dial down and used my bottom pin until it was dialed and made a mark...did the same at 60...

Now, I assumed that the sight tapes that Black Gold sent with the sights wouldn’t work because of my 550 grain arrow setup...I was right...what was interesting was that my gaps from 20-50 were equidistant...HOWEVER, the gaps from 50-60-70 started almost staking on one another...I shot like 8 rounds to confirm and it was confirmed. I know that heavy arrows will hold the KE longer than light arrow setups...it was just cool to see just how close my pin gaps were from 50-70 compared to what they were from 20-50...

Here are a few pics of my redneck sight tape...the top dot is where my sight sits during hunting (3-pins for 20, 30, and 40) The next two marks are where my bottom pin (floater) is dialed in at 50 and 60...you can see how close the 60 mark is to the 50 mark...I didn’t mark the 70 because it was just hard to believe how close it was to the 60, so I’m gonna shoot it again later this week and just re-re-confirm

Have any of you other heavy arrow fellers experienced this?

That is very interesting. You think the arrow would still have enough force behind it past 50 yards to make a clean killing shot?

I'm not advocating shooting a deer that far but am just curious.

Yes for sure. People kill large game animals all the time past 100 yards with modern archery equipment

I do...the amount of momentum I have with my personal setup, I would feel comfortable taking a 70-80 yard shot on a calm bull or muley out West...these crazy crackhead midwestern Whitetails—-not so much
 
I’ve got a similar sight this year. No luck on finding a tape that matched up? Just curious before I go through the headache trying to find one. Was planning on sighting in at 20/30/40. Step back to 50 and if shooting low, go to a slower tape. Did you find that they didn’t send a slow enough sight tape? What is your draw length/poundage?
 
I found a similar problem on my apex pro covert sight. The tape i went with is dead on from 20 to 37,after that my POI is higher than the tapes Numbers the further out i go.
It is no problem for my hunting distance and for practice it is pretty easy to figure out the difference at distance. I shoot 60# at 29.5 DL.

28.5 DL
65#

The plan was shoot 20 and 60, make marks, and then match those marks to the appropriate tape...i found the tape that matched my 20 and 60, the problem was that the tape that matched 20 and 60 was pretty far off when it came to the other numbers...because from 50-70, the heavy arrow pin gaps were so tight for whatever reason...hope that makes sense.

That’s interesting...we had similar issues then! What is your total arrow weight?

Yeap, so did you just end up marking by hand on sight? Or make your own tapes?
 
I have similar issues, shooting 600 gr arrow out of a 70lb bow @ 27". Most sight tapes from the manufacturer are calculated based off of arrow speed and they use some pre-determined constant factor to account for wind resistance. Since heavier arrows carry more intertia, they don't slow down as much due to wind resistance. At some given distance the trajectories of the heavier and lighter arrows intersect. Your tigher marks are a direct manifestation of that.

Slower sight tapes will match up better at closer distances but will be way off at long distance and conversely faster sight tapes will be way off at closer distances but will more closely mimic your trajectory at longer distances.

I've thought about making my own tapes and/or building software to do it for me, but instead of reinventing the wheel I just use a faster sight tape and call it "close enough". I don't see myself taking a shot on a live animal at those distances where the faster sight tape deviates and save those distances for practice only.

That makes sense. Glad I’m not the only one experiencing this...I’m far from a physicist, but I figured some smart feller could explain why I was getting the results I was getting...I considered using a slow sight tape from 20-50 and a fast sight tape from 50-100, but just seemed like a lot of work, so I went with the ole trusty silver sharpie...if you end up making the software for heavy arrow sight tapes let me know :)

That’s what I was gonna do, just Frankenstein 2 tapes bet you could get awful close.........
 
I’m getting this too. My 20-30y gap is different than the rest, I’ll put a pick of my sight tapes below. After that there’s only .04” difference in my 30-40y and 50-60y gap. TAW 550gr from 27.5” draw Vertix at 65#.

Sounds like someone needs to start making custom tapes... I have a label maker here at work. Just need to know spacing of yardage tics.
 
I get tapes from Lancaster archery and use them. This one works for my set up perfectly. I don’t see the Lancaster archery brand on their page any more but I’ve tried the gunsight ones in the past and they worked as well.


If anyone needs sight tapes hit me up, I have quite a few and would gladly pass them along.

i feel like if more and more people keep switching to heavy arrows, manufacturers will adjust accordingly. this was my worry for the ez-v sight too with my 670gr arrows. i just stick with my fixed 3 pin sights so i dont have to mess with tapes. 15-25-35 yds
 
I find hha tapes suit 500-600 grain arrows At 250-300fps well - better than I can shoot. All the way out to 100. While I might be an inch or two off at 50-100 yards, I don’t shoot well enough to notice the difference. What matters to me is grouping consistently at those distances. It means I’m doing things right.

Maybe I’m just getting lucky.

Lots of variables go into arrow trajectory, manufacturrrs are playing it right down the middle. I would be a happy camper if I shot well enough beyond 50 yards to notice if my tape was off! I should be clear too - I’m consistently shooting an inch per yard group (30-3”, 60-6”, etc.) Out to 100. I don’t think this is excellent, but I think it’s Better than 90% of folks, and it’s certainly good enough for hunting.

Can you clarify something for a dumb redneck? I'm reading your post as saying that your pin gap tightened as you went further out. Is that right?
