Setting the Correct Speeds

Post by Team Kusza » Tue Sep 03, 2019 4:46 pm

Hello there,
We just joined the forum and will be sighting in our crossbows in the next few days...
My son and I just purchased a Micro Suppressor and a Bulldog 440. They have the Tact Zone and Tact 100 scopes mounted on them respectively.
My son will be target shooting Quill 16.5" bolts and I will be target shooting Diablo 18" bolts and we will both be using 150 grain field points. We will both be hunting with the Luminok versions of these bolts coupled with 150 grain BAT Boltcutter broad heads.
We would like to know what speeds should we set on the speed dials of our scopes. The Suppressor is equipped with all the sound deadening devices on it that came from the factory and I added just the air brakes to the Bulldog.
Any guidance and/or suggestions would be much appreciated.
Thanks in advance,
TK

Congrats on the new bows, and welcome to the forum.
Set zero at 20 yards, move target to 40 yards and shoot at a dot near the top using the center reticle. The arrow will hit low so you might need to stack two targets for this. Now line up the center reticle on the dot and zoom the dial to the arrow and correct scope marker. Don’t be concerned what the dial says, it is reference only.

Good luck, and enjoy.

Interesting Suggestion.
As the poster I to am getting ready to setup a NEW Micro 360TD Pro for the first time this Thursday.
I plan to try your suggestion. .
I have always followed a method I came across years ago which I believe was suggested by Bill T.
In a video which the target ismsetup using the 20 and 50 yds distances
First I would set the speed ring to the approximate speed as indicated in the specification for the crossbow model.
Then setup my 20 yd zero first using the windage and elevation adjusters
Then moved target out to 50 yds and then using the 50yds scope mark shot at the bullseye spot on target.. Then adjusted speed ring up or down as needed until arrows hits the 50 yd spot on the target.
Then move target back to 20 yds and fine tune the 20yd zero using the windage and elevation .
adjuster. again.
Then I would move the target back out to 50 yds and fine tune speed ring if needed.
Then shot three arrows at each distance 20/ 30/ 40/ 50 / and now 60 to confirm zero at all distances This whole process usually takes a couple hours.
Your method seems like a lot less work :thumbup: and shots required will give it a try.


Thanks

You can do 50 yards if you want to, it's just that most hunt out to 40 yards. It's not perfect, but yes it's quick & pretty darn good. It's like setting a scope on a gun, aim at bulls eye, shoot, hold on bulls eye & adjust to bullet hole. I recommend using a good rest for this process! :thumbup:

To answer your question about what speed to set the scopes for initially I would set the speed dials about 20 fps slower than the rated speeds for the bows. Then follow the above directions.

I basically follow Dan's method (xcaliber) and it makes for a quick job.

Here are some things to remember and tips I learned along the way.....


The speed ring will not affect the 20yds zero at all. You are really only adjusting the magnification power of the scope, therefore the reticle at the center of the scope is not affected.

#1 - make sure the scope is dead level on the crossbow. I put a level on the limbs to make sure the bow is level, then put a small one on the scope to make sure it is level. Another way is to hang a big rope with a weight (plumbob) and while keeping the bow level, align the verticle reticle to the rope.

#2 make sure the bow is level when you shoot it.

Be meticulous with your 20yd zero. Make it as perfect as you can, hitting EXACTLY where the cross-hairs are. This makes things easier later.

Fine tune the windage adjustment at a farther distance (40 or 50) as that will be more accurate
