Rifle scope on a crossbow ?
« on: September 03, 2009, 01:42:44 AM »
Hello from Georgia,

  I have heard that a crossbow will destroy a rifle scope in short order. I would like to know if this is true, and if so why. If a scope can tolerate the recoil from a 405 gr. 45/70 loaded hot, why is the recoil from a bow more damaging. I am thinking it may be the same reasoning as a pellet gun? What about a red dot scope ? What makes them more tolerable to the crossbow recoil. And also, what difference is there between a "regular" scope and a "crossbow" scope. Would the latter be better for a heavy recoiling rifle, or a 3" mag. slug gun? I am 100 % sure that my Horton crossbow will never kick as hard as the NEF single 45/70 ThunderBoomer. Kinda curious about the whole "recoil dynamics". Thanks.

Dave

I don't know for sure but from what i have read and heard it is the vibration
more than recoil.

I would expect that as you said it may be similiar to an airgun and the type of recoil that kills scopes. My brother has a cheap red dot on his that has held up for about 5 years now, longer than I thought it would. The crossbow scopes I've seen have a range-estimating reticle with multiple lines,not sure of their internal construction.

Great question!  I've wondered this too and always heard you shouldn't do it that the scope wouldn't hold up but never heard the why.

I have used a cheap simmons 4x scope on my Horton crossbow with no problems for over 5 yrs now. Took my biggest 10 pt buck with it several years ago. I was very confident with accuracy with that set up.

I think someone is blowing smoke up your butt there Dave ,

 Your logic is my logic .. If a nikon can handle my 3700 lbs of energy at the muzzle 444 marlin hot loads why on this green earth would a X-bow damage it unless you place it in front of the bolt heh ...

 Guy i worked with said his hunting buddy has been using the daisywal mart cheapy red dot on his X-bow for years and works great and saw no reason to change it till the little thing gave up the ghost ..


  Think that says it all ;)

I contacted BSA,as I have a 3x9 illuminated scope on my excalibur phoenix.They state that it will hold up fine.I have only shot it about 25 times since I mounted it,so time will tell. I did take a nice doe with it. I sighted it in at 25 yards.

I couldn't adjust my scope enough to get it to sight in.  I put a red dot from my paintball gear on it.  Killed a small 8 point @ 18 yards.

  I have never had a scope or red dot keep its mark with a crossbow. All stock scopes and red dots from Barnett and Horton have been deplorable. I currently use a pin and peep from PSE and have had no problems.

Hello,

   I finaly got a response from the people at Horton, and they say that the recoil dynamics from a crossbow will indeed destroy a "regular" scope. They however did not have an explanation as to the difference of a "crossbow" scope. This is similiar to the claims that a pellet gun will ruin a scope that would otherwise be fine for a centerfire rifle, yet if you use a "pellet gun" scope, all will be fine. Nevertheless, I have since put a red dot aperature on it and it is as accurate as it has ever been. As a sidenote, Robert Gradous, a world class riflesmith who lives near me says that there is no way a crossbow could destroy a good rifle scope. So, my investigation will continue until SOMEONE  can explain how a crossbow and pellet gun is different from a regular rifle scope.

Best ones I have found are the same as those for an air gun, it was explained to me that the foreword/backward bounce recoil is what tears up the scopes. Closest one I have come to working for a long while is a Simmons Shotgun scope

Many years ago I put a cheap 1.5 power Tasco on my Horton Supermag that was on a 12 ga slug gun before.  After a few years on the slugger, it started shifting impact at each shot.  Had it on the Supermag for 5 years and the only time it changed POI was once when I accidentally dry fired it.  I think a good quality, low power wide angle scope should last a long time on one.  Currently have a Barnett red dot for the last 3 years with no problems and I shoot it a LOT!  Just my experiences....
